Module 23 Notes: Dealing With Substance Abuse in the Workplace

Section 1: Introduction & Background

• Overview of Cognitive Behavioral Therapy (CBT) for substance use disorders
  • CBT demonstrates efficacy as both a monotherapy and as part of combination treatments.
  • Core elements across protocols include: operant learning strategies, cognitive and motivational elements, and skills-building interventions.
  • Across protocols, core elements focus on overcoming the powerful reinforcing effects of psychoactive substances.
  • Evidence supports core elements across a heterogeneous set of protocols.
• Substances used in South Africa (SA): tobacco, alcohol, cannabis, and various illicit drugs.
  • Tobacco: cigarette consumption declined by about a half between the early 1990s and 2004, attributed to tobacco control legislation and taxation. ext{per capita consumption} o ext{about }50 ext{ ext% reduction}.
  • SADHS findings (1998–2003): smoking among men declined from 42% to 35%; among women from 11% to 10% (note: sampling differences may affect gender-race comparisons). Urban areas show higher smoking rates than rural; Northern and Western Cape reported highest smoking rates.
  • Alcohol: SA estimates ~28 ext{ ext%} of the population; ~7 ext{ ext%} classified as 'high risk' by AUDIT. SADHS 2007: current drinking levels 30% for men and 10% for women (likely underestimates; SADHS 1998 reported 45% of men and 17% of women current drinkers).
  • Drinking patterns by race/region: White population highest consumption; African population lowest; hazardous drinking highest among Coloured individuals and African males. Urban areas again show higher current drinking than rural areas.
  • Cannabis: most common illicit substance in SA; about 2 ext{ ext%} of adults use cannabis; higher use among adolescents; higher rates in urban areas; higher among Coloured and White population groups.
  • Other substances (SA trends): polysubstance abuse remains high (≈32–45% report more than one substance). SACENDU tracks trends via treatment centres; alcohol remains the most common primary substance among patients in treatment; cannabis is the most common illicit drug.
  • Regional variations: in Western Cape and northern regions, methamphetamine (tik) and cannabis (dagga) are primary drugs of abuse; heroin use rising in Gauteng, Mpumalanga; crystal methamphetamine use rose notably in Cape Town (2003–2006).
  • Gender differences: overall SA males have higher rates of alcohol and drug use; females more likely to abuse OTC and prescription medicines (e.g., benzodiazepines, codeine).
• Addiction: foundational definitions and characteristics
  • Addiction defined as the use of substances for a variety of reasons, including pleasure, stress relief, or reality alteration; includes misuse of prescription drugs or use of someone else's prescription.
  • Addiction is a primary, chronic disease of brain reward, motivation, memory and related circuitry, leading to biological, psychological, social, and spiritual manifestations.
  • Key characteristics of addiction include: inability to abstain consistently, impaired behavioral control, craving, diminished recognition of problems, and dysfunctional emotional responses.
  • Addiction often involves cycles of relapse and remission; without treatment, it is progressive and can lead to disability or premature death.
• Characteristics of Addiction
  • Compulsive Use: Blume (2005) identifies three elements: reinforcement, craving, and habit.
  • Reinforcement occurs when the substance/behavior provides pleasure or relief from pain/stress.
  • Tolerance develops with continued use, requiring larger doses for the same effect.
  • Habit results from deeply ingrained patterns in the nervous system; addictive behaviors often become automatic responses.
  • Physical Craving: body and brain signal that the drug/behavior is needed; ongoing use disrupts brain chemical balance.
  • Withdrawal: cessation leads to unpleasant, opposite effects of the drug; withdrawal can be life-threatening if not monitored; alcohol withdrawal can progress to delirium tremens with seizures, disorientation, or death.
• Loss of Control
  • Addicts often cannot predict how much or when they will use, and cannot stop once begun.
  • Impairment of judgment and planning (e.g., alcohol myopia) can occur in intoxication, reducing ability to evaluate the environment effectively.
• Continued Use Despite Adverse Consequences
  • Denial is common; the pleasurable effects may overshadow negative consequences.
• Physical and Clinical Implications in the Workplace
  • Alcohol and drugs in SA workplaces impact safety, productivity, and morale.
  • Substance use correlates with absenteeism, injuries, accidents, reduced performance, increased turnover, and possible illegal workplace activities (e.g., selling drugs, bribery).
  • OHSA (Operational Health and Safety Act) provides a duty for employers to stop employees from entering a site if under the influence; emphasizes substance-free workplaces and EAPs.
• Alcohol and Drugs in the Workplace: Introduction
  • Substance abuse affects job performance and safety; employers can aid prevention, intervention, and recovery through policies and programs.
  • Workplace costs include absenteeism, reduced productivity, safety risks, higher turnover, training costs, and potential legal/regulatory exposure.
• Effects on Workplace (Key Impacts)
  • Premature death or fatal accidents; injuries and accident rates rise due to impaired judgment and concentration.
  • Substance abuse is a risk factor for workplace violence; employees who abuse substances are more likely to have injury-related absences.
  • Overall productivity may drop; industry data suggest a significant impact on efficiency and safety.
  • Co-worker effects: higher workloads, stress, conflict, and lower morale; potential for theft and other misconduct.
• Alcohol Use in the Workplace
  • Problem behaviours arise from drinking immediately before/during work or heavy drinking the night before causing hangovers.
  • Industries with higher workplace alcoholism include construction, excavation, food service, installation/maintenance/repair, mining.
• How an Alcoholic Employee Behaves (Phases)
  • Early Phase: increased tolerance, attendance and performance changes, drink to relieve tension; visible signs include lateness after lunch and fatigue; behaviors include lying about drinking and complaints of not feeling well.
  • Middle Phase: surreptitious drinking, guilt, tremors, loss of interest; signs include frequent days off, unreliable statements, borrowing money, hidden intoxication.
  • Late Middle Phase: discussing problems avoided, control issues, neglect of meals; signs include extended time off, erratic attendance, aggressive behavior, loss of ethical values, financial issues.
  • Late Phase: substance abuse dominates work life; prolonged absences, drinking on the job, severe unreliability, physical deterioration, serious personal problems.
• Drugs in the Workplace
  • Six General Symptoms of Addiction in the Workplace (not enumerated in the transcript).
  • Specific Drugs and Signs of Abuse: Cocaine and other stimulants; Heroin; Marijuana; Valium.
• What the Workplace Can Do
  • Develop a substance-free workplace policy; consult with management, unions, EAP providers, and addiction specialists.
  • Policy should clearly define substance abuse, purpose/objectives, coverage, confidentiality, behaviors requiring response, handling prescription medications, coworker concerns, violations, testing, consequences, employee assistance, review processes, and management responsibilities.
  • Policy should be linked to risk assessment and safety needs; may be part of a larger occupational health and safety framework.
• Policy Components and Risk-Based Content
  • Aims and objectives: prevent drug- and alcohol-related incidents; promote safe work behaviors.
  • Scope: applies to all workers, contractors, interns, volunteers, etc.; equal treatment and non-discrimination.
  • Workplace-specific content: include identified risks, testing regimes, and policies for work-sponsored events.
  • Identification and management: clear criteria for identifying affected workers; decision on who identifies; supervisor training to recognize changes and respond empathetically.
  • Self-assessment: workers should not report to work if intoxicated; no stay-at-work if affected.
• Consultation, Education and Awareness, Evaluation
  • Consultation with management, workers, and representatives to determine policy needs; open participation improves credibility and acceptance.
  • Education and awareness: provide information on risks, services, resources, and accessible programmes; address stigma; communicate policy existence and contents; ensure resources are available.
  • Ongoing information and training; management support demonstrated.
  • Evaluation: assess outcomes, affected workers, policy effectiveness, treatment efficacy; ensure accountability; consider testing regimes as part of policy decisions.
• Drug and Alcohol Testing in the Policy
  • Consider including a testing regime based on risk assessment and consultation; testing should be voluntary, confidential, and non-discriminatory per law.
  • Testing methods may include breath tests, blood tests, and field observations; consent must be obtained in writing; witnesses may accompany testing; keep records of observations (appearance, attitude, signs, etc.).
• Assessment of Workplace Risks (Risk Assessment)
  • Identifies high-risk environments (e.g., machinery, hazardous materials, underground settings) and whether organizational culture promotes use.
  • Considers accessibility, possible peak exposure to alcohol at work (e.g., licensed premises), and potential safety and health impacts.
  • Scope and goals of the policy; annual reviews; communication with employees; wellness programs; employee feedback; inclusive events; training requirements; stigma reduction.
• Education for Employees
  • Goals: reduce stigma; raise awareness of safety and performance impacts; explain policy and responsibilities; connect to broader wellness programs.
  • Resources: pamphlets, videos, and books on substances and related support resources.
  • Expert speakers and partnerships with benefit providers or addiction agencies.
• Identifying Employees with Problems
  • Tools include Breathalyzer and field sobriety tests; ensure lawful, fair testing with calibrated equipment and proper procedures.
  • Case law examples emphasize that testing alone is not always sufficient; corroborating observations and proper procedures are essential to uphold fairness.
  • Management training to identify changes in performance and behavior; encourage use of EAPs and rehabilitation options instead of immediate discipline where appropriate.
• Assistance, Treatment and Rehabilitation Programs
  • Treat employees with alcohol or drug problems fairly; provide access to counselling, treatment, and rehabilitation; allow for reasonable accommodations (time off, transfers) where feasible.
  • Employees undergoing treatment remain subject to normal disciplinary rules for other offences; treatment programs do not automatically exempt from discipline for new offences.
  • Size of the company affects program delivery (e.g., EAPs in larger companies vs. referral to external services in smaller firms).
• Principles of Effective Treatment
  • Addiction is a treatable, complex disease; no single treatment fits everyone.
  • Quick access to treatment is important; address all patient needs, not just drug use.
  • Prolonged treatment duration improves outcomes; ongoing assessment and adjustment of treatment plans is essential.
  • Medical detox is only the initial stage; address potential comorbid mental health disorders; monitor drug use during treatment.
  • HIV/Hepatitis screening and risk-reduction education should be part of treatment planning.
• Drafting a Company Policy
  • A tailored policy is essential; one-size-fits-all policies are ineffective.
  • Rules must consider job-specific risks (e.g., hazardous occupations vs office roles).
  • The policy should address alcohol use off-site during work-related events and at work-sponsored functions.
  • Identify an affected person with clear criteria; specify who identifies; provide supervisor training.
  • Self-reporting ethics and procedures; avoid blanket zero-tolerance policies that push problems underground.
• Warnings and Disciplinary Proceedings
  • Progressive discipline is typical: verbal warning → written warning → final written warning → dismissal.
  • Warnings must include: parties’ identities, offense details (nature, date, time), warning terms and validity, required corrective actions, and consequences of non-compliance.
  • Warnings can be verbal, written, or final written; formal processes apply when necessary and must be fair.
  • The specific sequence may vary if an employer’s disciplinary code prescribes a different progression, but the underlying principle is to correct behavior before termination.
• Section 2: Subsection on SA Law and Incapacity
  • In terms of OHSA regulations, employers must prevent intoxicated individuals from entering or remaining at the workplace.
  • Distinction between misconduct (improper conduct) and incapacity (ill health) is important; some alcohol- and drug-related issues may be treated as incapacity and require counseling/rehabilitation rather than immediate dismissal.
  • The line between intoxication and alcoholism is nuanced; alcoholism is a medical disease and may require treatment rather than punishment.
• Examples and Case Law (Section 2)
  • Example 1: Transport and Allied Workers Union of SA v. Dabula/Algoa Bus Company (2013) – breathalyzer reading 0.84, eight times the limit of 0.10; employer’s zero-tolerance policy; issues with reliability of testing, lack of corroborating observations; court affirmed dismissal as fair due to policy compliance, but noted the need for corroboration and proper observation.
  • Example 2: Metal and Electrical Workers Union of SA v. Setshedi/Scaw SA (2012) – tests read above 0.05% BAC; multiple readings; long service; employer’s policy upheld, but case underscored need for proper testing protocol and representation during testing; ultimate outcome favored employer given policy and circumstances.
  • Example 3: Transnet Freight Rail v. Transnet Bargaining Council & Others (2011) – Louw dismissed for reporting to work under the influence in a safety-critical role; controversy over EAP counseling mandate; Labour Court emphasized difference between misconduct and incapacity; ordered reinstatement with compensation and rehabilitation directed under EAP; highlighted the limits of a commissioner ordering rehabilitation when not applicable.
• Case law synthesis: Misconduct vs incapacity (blurred lines)
  • Alcoholism is treated as a disease in medical contexts; the line between intoxication and addiction depends on fault and capability to manage consumption.
  • Courts caution against converting all alcohol-related incidents into alcoholism-based incapacity; context, job risk, and safety considerations are critical.
  • Final warnings are meant to be final; continuing to work while under the influence, particularly in safety-sensitive roles, may justify dismissal rather than rehabilitation alone.
• Practical guidance from the Transnet and related cases
  • Employers should implement: an EAP, a comprehensive substance-abuse policy, and appropriate testing protocols that align with law.
  • Documentation and evidence are critical; rely on a combination of observation, testing, and whether the employee acknowledges the problem and seeks help.
• Legislation and Policy Framework (overview)
  • The Constitution: prohibits unfair discrimination on disability, including substance dependence; protections relevant to treatment and accommodation.
  • Prevention of and Treatment for Substance Abuse Act (2008): recognizes chronic, relapsing nature of substance abuse; supports prevention, early intervention, treatment, and reintegration; establishes treatment centers and research centres.
  • Occupational Health and Safety Act (Regulation 2A): duty to ensure employees under the influence are not allowed to work; requires safety-first approach and measures to maintain a safe workplace.
  • Compensation for Occupational Injuries and Diseases Act: employer and employee responsibilities for safety; cannot claim compensation for damages from self-induced intoxication in some cases; emphasizes employer responsibility for safety.
  • Employment Equity Act: allows for testing under lawful/medical justifications or inherent job requirements; random testing must be voluntary, confidential, and non-discriminatory.
  • Labour Relations Act: labour courts distinguish between incapacity and misconduct; drinking while on duty can be misconduct or incapacity depending on context; discipline procedures differ (disciplinary vs rehabilitation pathways).
  • The South African Labour Guide: no single policy fits all; advocates de-stigmatizing dependence while recognizing the need to discipline for misconduct when appropriate.
• Workplace Substance Abuse Policy Guidelines (ILO and SA context)
  • ILO guidance highlights measures to reduce problems, restrict availability, prevent problems through info/training, identify and refer individuals for help, intervene and rehabilitate, enforce conduct rules, and ensure equal opportunities.
  • Non-discrimination and confidentiality are core principles when implementing substance abuse policies.
• Section 3: References (Overview)
  • The module cites a wide range of sources, including Sidumo v. Rustenburg Platinum Mines Ltd, various SA Labour Court decisions (Transnet cases, Dabula, Setshedi, Mabane-related cases, Metrorail/SATAWU contexts), and multiple acts and international sources.
  • It also references SACENDU trend analyses, SA Demographic and Health Surveys, HSRC publications, and UN/ILO guidelines relevant to workplace substance abuse policy.
• Practical implications for exam preparation
  • Understand the differentiation between impairment-based misconduct and disease-based incapacity, and how policy, procedure, and evidence influence fairness of discipline.
  • Be able to articulate core components of an effective substance-free workplace policy, including testing protocols, risk-based tailoring, consultation processes, education/awareness, and evaluation.
  • Know key SA laws that influence workplace substance abuse management, especially OHSA Regulation 2A, the Prevention of and Treatment for Substance Abuse Act (2008), and the Labour Relations Act item 7 and item 10 considerations for misconduct vs incapacity.
  • Recognize practical testing approaches (breathalyzer, field sobriety tests) and the importance of corroborating observations, proper procedure, and documentation.
• Final takeaway
  • A balanced, legally compliant approach combines prevention, education, supportive treatment pathways (EAPs), and fair disciplinary measures, tailored to specific job risks and supported by documented policy and consistent procedures.

Section 2: Substance Abuse in the Workplace and SA Law

• Incapacity Code and Procedures in respect of Poor Performance
  • Examples illustrate how courts weigh abstinence, impairment, and safety-critical duties when determining misconduct vs incapacity.
  • Example 1 (Dabula/Algoa Bus Company): breath test showed 0.84 BAC; zero-tolerance policy; issues with evidence reliability and lack of corroboration; emphasis on policy-consistent discipline and fair procedure.
  • Example 2 (Setshedi/Scaw SA): two breath tests yielded readings just above 0.05%; long service; court treated testing protocol, representation, and policy consistency as critical factors; upheld dismissal under policy.
  • Example 3 (Transnet Freight Rail): Ms. Louw dismissed while in a safety-critical role; arbitration favored reinstatement with rehabilitation focus; emphasized proper use of EAP and consideration of final warnings.
• Process-based and outcome-based review (Sidumo framework)
  • The concept of latent irregularities in arbitration—process-based review—requires arbitrators to apply evidence law, substantive dismissal law, consider all relevant factors, and avoid irrelevant factors.
  • The Transnet decision reaffirms that Sidumo does not grant blanket authority to disregard process fairness; the entire process must be fair to both parties.
• Case synthesis and practical implications
  • The boundary between misconduct and incapacity is fact-specific; alcoholism as disease can factor into incapacity in some cases, but not all intoxication cases qualify as incapacity.
  • Employers should design processes that allow for rehabilitation when appropriate, while preserving safety-critical standards and maintaining clear disciplinary rules for misconduct when rehabilitation is not feasible.
• Drafting and applying a workplace policy (SA legal landscape)
  • A robust policy includes clear rules, testing provisions, procedures for identification and intervention, and alignment with SA law.
  • When implementing, ensure that employees understand their rights (consent for testing, representation), and that disciplinary actions are proportionate and justified by evidence.

Section 3: References (Overview)

• Core legal and policy references include:
  • Constitution of the Republic of SA: protecting against unfair discrimination (including disability/incapacity related to substance dependence).
  • Prevention of and Treatment for Substance Abuse Act (2008): framework for prevention, treatment, rehabilitation, and reintegration; supports treatment centers and information management.
  • Occupational Health and Safety Act: Regulation 2A (employer duty to prevent intoxication at work; define zero-tolerance expectations and safety provisions).
  • Compensation for Occupational Injuries and Diseases Act: employer/employee responsibilities for safety, with considerations for intoxication-related injuries.
  • Employment Equity Act: testing allowances under lawful/medical justifications or job requirements; random testing must adhere to voluntary, confidential, and non-discriminatory principles.
  • Labour Relations Act: distinguishes between misconduct and incapacity; safety-critical roles emphasize protection of workers and the public; appropriate use of EAP and rehabilitation where alcoholism or dependency exists.
  • South African Labour Guide: stresses no one-size policy; emphasizes stigma reduction and rehabilitation-based approach where appropriate.
  • ILO guidance on workplace policies: measures to reduce problems, restrict availability, educate, identify and refer, intervene, and ensure nondiscriminatory practices with confidentiality.
• Case examples cited in the module include: Transnet Freight Rail v. Transnet Bargaining Council & Others; Dabula/Algoa Bus Company; Setshedi/Scaw SA; Mabane and related labor court decisions; and related arbitration outcomes (Metrorail, Lucas/Orex Spoornet, etc.).
• Additional scholarly and statistical sources cover SACENDU trends, SA Demographic and Health Survey data, HSRC reports, medical and addiction research, and UN/WHO sources relevant to policy and public health implications.

Section 4: Key Concepts to Remember for Exam

• Distinction between misconduct and incapacity, and how addiction may be treated under different procedural paths depending on facts (job risk, alcoholism diagnosis, and evidence).
• Core treatment principles: accessibility of treatment, addressing multiple patient needs, duration of treatment, integration with HIV/hepatitis risk education, and the role of medically assisted detox as a first step—not a sole solution.
• Policy design principles: tailoring to job-risk, ensuring fair identification and testing processes, and including education, confidentiality, and regular policy reviews.
• Legal and practical testing considerations: consent in writing, witness presence, calibration and reliability of equipment; the need for corroborating observations (appearance, attitude, or behavior) in addition to test results.
• Rehabilitation-first approach in appropriate cases, with clear escalation when rehabilitation is not feasible or when safety-critical duties are involved.

Section 5: Quick Reference (Key Numbers and Terms)

• BAC threshold examples: 0.05 ext{ ext%} as a common limit for impairment in some cases; 0.10 ext{ ext%} as a cited breathalyzer threshold in examples; observed reading of $0.84$ as eight times the 0.10 limit: $0.84 = 8 imes 0.10$.
• High-risk drinking indicators via AUDIT: ext{AUDIT}
  ightarrow ext{high-risk classification} (specific cutoff values vary by protocol).
• SA prevalence data: approx 13.3 ext{ ext%} of SA adults struggle with addiction; description of risk factors and health system impact.
• Industry examples of problem areas: construction, mining, food service, etc. where alcohol use significantly affects safety and productivity.
• Policy components: definitions, scope, testing, confidentiality, consequences, EAP, and policy review timelines.

Section 6: Hypothetical Scenarios (for practice)

• Scenario A: Employee arrives at work smelling of alcohol with a BAC around 0.05 ext{ ext%}; the company policy prohibits reporting to work under any intoxication. Consider next steps: immediate testing, supervisor notification, documentation, and possible disciplinary action aligned with policy, while offering EAP support.
• Scenario B: An employee in a safety-critical role reports to HR with a dependency issue and agrees to enroll in an EAP program; what are appropriate accommodations, and how should performance be monitored during treatment?
• Scenario C: A long-tenured employee tests above the threshold on two separate occasions but claims alcoholism; how should the employer balance discipline with potential rehabilitation and safety obligations? Consider EAP, possible temporary reassignment, and documentation.

Section 7: Quick Glossary (terms you should know)

• AUDIT: Alcohol Use Disorder Identification Test; screening tool for high-risk drinking.
• OHSA: Occupational Health and Safety Act; regulatory framework for workplace safety and related controls.
• EAP: Employee Assistance Program; employer-provided or contracted program for counseling and rehabilitation.
• EAP-directed rehabilitation: a structured path for employees with addiction to recover while maintaining employment whenever feasible.
• Incapacity vs Misconduct: incapacity relates to ill health or impairment impacting work capacity; misconduct relates to fault-based violations of rules or policies.
• SACENDU: South African Community Epidemiology Network on Drug Use; tracks trends in SA substance use and treatment demand.
• Field sobriety tests: non-invasive tests (e.g., horizontal gaze, walk-and-turn, one-leg-stand) used to assess impairment.
• Final written warning: a serious disciplinary step indicating final opportunity before dismissal.
• Safety-critical position: a role in which impairment poses immediate risk to safety of the employee or others.

Section 8: Summary of Practical Takeaways

• A well-designed workplace policy should balance safety, fairness, rehabilitation, and legal compliance; tailor it to job risk and organization size.
• Testing (breath, blood, field sobriety) must be properly controlled, with written consent, witnesses, and corroborating evidence to ensure fairness.
• Distinguish between misconduct and incapacity; use EAP and rehabilitation when appropriate, especially in safety-critical roles.
• Education and awareness reduce stigma and encourage help-seeking; ongoing evaluation ensures policy effectiveness and alignment with laws.
• Case law emphasizes process fairness and careful application of the law to ensure that disciplinary actions are justified and proportionate.
