Provides access to a core social role in adult life- Continuous salary, wage (economic independence)
- Social status and socioeconomic security
- Prestige, social identity
Enables meeting of demands- Motivation of agentic self, structuring of time
- Success, self efficacy
- Continuous learning, skill development
Offers reward, recognition, and belonging
- Enlarged social network (beyond family)
- Social support and cooperation
- Recognition of achievement
Work has the potential of maintaining and
promoting mental health!
Continuous automatisation of production
Microelectronic revolution of information and communication technologies
Increase of service and IT sectors within the labour market
High prevalence of psychomental and socio-emotional stress at work
Growth of flexible and precarious employment, work-life imbalance
Job instability and insecurity, forced mobility
High work pressure, often related to economic globalization
Modern working life carries opportunities and
risks for mental health!

Challenges
In view of the burden of reduced mental health in
general, and of depression in particular, across
European working populations:
1. What is the role of stressful work in increasing the risk of incident poor mental health?
– How can we identify and define stressful work?
– How can we provide scientific evidence?
2. What are the policy implications of current knowledge for improving mental health at work?

• Procedural justicePerceptions of consistent, accurate, unbiased and
ethical rules of procedures
• Relational justicePerceptions of polite, fair interactions from
supervisors
• Distributive justicePerceptions of appropriate distribution of job tasks
and gains among employees

Relevant study design: Prospective observational cohort study
of working populations who are free from mental disorder at
baseline.
Study aim: Demonstrating elevated relative risks/ odds ratios of
mental disorder as a function of exposure to work stress
Additional evidence on pathways:
Experimental and ‘naturalistic’ studies linking work stress with
psychobiological markers related to disorder
Measuring work stress:
Psychometrically validated scales/ questionnaires

Conclusions
• Robust scientific evidence that unhealthy work (DC, ERI,
OJ) is associated with an almost twofold elevated
relative risk of poor mental health (depression).
• Overall, every fifth working person is exposed to
unhealthy work, with higher prevalence among those
with low SEP.
• These important human and economic costs can be
tackled by strengthening evidence-based prevention at
the level of companies and of national/international labor
and social policies.

Policy implications 1:
Organizational and personnel development
• Provide shared commitment from management and
employees
• Provide available expertise (e.g. occupational safety &
health)
• Monitor working conditions and employees‘ health, with
special emphasis on social inequalities
• Develop and implement programmes, invest in
improvements, consult models of best practice
• Ensure continuity, evaluate outcomes, build networks
Policy implications 2:
National/international initiatives
• Apply legal frameworks (national, international)
• Enforce fair work standards in trade contracts
• Promote voluntary agreements between employers and
trade unions
• Support social movements (e.g. EU: Corporate Social
Responsibility)
• Maintain and develop distinct national labor and social
policies
Welfare regimes securing basic social and economic protection,
access to health care, further education, etc.
