Study Notes on Job Stress: Characteristics, Models, and Implications

The chapter discusses job stress in relation to employee health, well-being, and performance.
**Key Questions:

Topics include:
- Job stress as a societal issue.
- Main perspectives on job stress including individual variability.
- Integrative process model of job stress.
- Four theoretical models of job stress:
1. Demand-Control-Support model.
2. Effort-Reward Imbalance model.
3. Job Demands-Resources model.
4. Demand-Induced Strain Compensation Recovery model.
The conclusion addresses transforming stressful work conditions into ‘healthy work’.

Concern in All Countries: Job stress impacts all levels of society, affecting employees, organizations, and society.
Changing Nature of Work:
- Globalization (the ‘24/7 economy’).
- Increased use of ICT.
- Workplace diversity (gender, age, education, migration).
- Flexible work arrangements; redesigned work processes.
- Shift from industrial to knowledge and service work.
Mental vs. Physical Stress: Increased workloads lead to stress being perceived more as mental and emotional rather than physical.

High Prevalence of Job Stress:
- Sixth European Working Conditions Survey (EWCS) reported:
- 27% of employees under tight deadlines.
- 23% work at very high speed.
Costs of Job Stress:
- Linked to burnout, depression, cardiovascular diseases, musculoskeletal disorders, chronic pain, absenteeism, reduced performance.
- Estimated costs for US companies: Hundreds of billions USD yearly due to job stress.
- EU’s costs of depression due to work stress: €617 billion in 2013.
Legislation: Increased laws focusing on psychosocial work conditions aimed at improving employee health and well-being.
- Key Elements of Labour Legislation:
1. Comprehensive approach integrating health and well-being.
2. Broad health concept (beyond absence of illness).
3. Employers and employees share responsibilities.
4. Supportive environments institutionalizing Occupational Health Services.

Definition and Origins:
Derived from engineering to describe external pressure causing tension—similar to physical stress in materials.
Adaptability: People can recover from stress; this adaptability varies based on personal and situational characteristics.
Interpretations of Stress:
1. Stress as a Stimulus (cause)
2. Stress as a Response (strain)
3. Stress as a Mediational Process between stimulus and reaction.

Job Demands: Things that require cognitive, emotional, physical effort (examples: workload, time pressure, role conflict).
Job Resources: Assets to address demands (examples: autonomy, social support).
Job demands can be categorized into:
1. Cognitive demands
2. Emotional demands
3. Physical demands
Job resources can also be emotional, cognitive, or physical.

Psychophysiological Definition of Stress: Stress responses are internal reactions to threats or demands.
General Adaptation Syndrome (GAS):
- Stages:
1. Alarm (physiological mobilization)
2. Resistance (optimal adaptation)
3. Exhaustion (depletion of energy).
Strain Clusters:
- Affective: Anxiety, sadness.
- Cognitive: Poor decision-making.
- Physical: Pain, fatigue.
- Behavioral: Changes in habits.
- Motivational: Lack of energy.
Intensity and Manifestation Levels: Stress can present as individual symptoms, interpersonal issues, or organizational problems.

Transactional Model: Stress reactions depend on person-environment interactions.
Coping Framework (Latack & Havlovic, 1992):
- Distinction between problem-oriented and emotion-oriented coping.
- Observable vs. non-observable coping methods.
Definition of Job Stress: Incongruence between job demands and resources causing cognitive, emotional, physical, or behavioral symptoms.

Stress Dichotomy: Selye identified stress as non-specific, where ‘distress’ is negative and ‘eustress’ is positive.
Eustress Re-definition: Viewed as a positive challenge that promotes growth.
Positive Psychology Movement: Goals include employee engagement, initiative, and responsibility.

Individual Differences: Employees vary in how they experience demands and cope with stress.
Categories of Individual Characteristics:
1. Dispositional (inherent traits).
2. Acquired (skills, education).
Influence on Job Stress: Some employees are more susceptible to stress due to personal traits.

Importance of Models: Job stress models simplify complex job characteristics impacting stress reactions.

Foundational Concepts:
- Job demands relate to exertion and control relates to autonomy.
- Karasek et al. proposed jobs lead to stress based on levels of demands and decision latitude.
- Job Classifications:
- High-strain jobs
- Low-strain jobs
- Active jobs
- Passive jobs

Concept Overview: Focus on the reciprocity between effort invested and reward received in the workplace.
Components of Effort: Extrinsic efforts (demands) and intrinsic efforts (overcommitment).
Health Risks: Imbalance correlates with stress-related health issues.

Framework Introduction: A blend of job demands and resources to predict health and motivation outcomes.
Processes: Health impairment process and motivational process.

Comprehensive Approach: Combines various principles from earlier models focusing on demands, resources, and the importance of work-life balance.

Summary of Changes: Work nature has shifted to mental and emotional demands, presenting unique stress challenges.
Addressing Job Stress: Models suggest interventions should primarily target job-related sources of stress and enhance job resources.
