Healthy Workplaces Summit 2013

Working together for OSH - successful organisational and individual interventions

Rüdiger Trimpop, University of Jena

  • When and for whom is participation necessary?
  • Which hazards cant be reduced without participation?
  • Who needs which increased knowledge?
  • What is the perception of leadership?
hierarchy of success and participation
Hierarchyofsuccess and participation!
  • Thereareapproachdifferences in OSH in Europe:
  • Northern Countries:Participation plus Leadership plus Work design
  • Middle Countries: Work design and Control plus Leadership
  • Southern and Eastern Countries: Person centered and Control
  • Comparison Former East vs. West Germany
  • Similarsafetystandards through different approaches
  • Participativeapproach versus technicalapproach
change of hazards and loss time
Change ofHazards and Loss Time

In thepast, themajorfocus was on productionindustrywith a strong emphasis on avoidingworkaccidents.

  • This type ofaccidenthasdroppedsignificantly, partlybecauseofeffective OSH partlybecauseaccident-pronejobshavebeenautomatizedoroutsorced.

Manysuccessful large companieshaveinstalled OSH Management Systems and changedthework design. Successfulsmallcompaniesrely on leadership and safetyadvicefrom outside.

However, thefocusofHealth Promotion and Preservationisshifting!

new threats
New Threats!

The twomajorsourcesfordeadlyaccidents and time loss in many European countries are:

Occupationaltrafficaccidentshave not beenreduced and accountformorethan 50% of all deadlyaccidents. Tendencyrising!

Occupational Stress accountsformanyhealthproblems and isrelatedto 40% oftheloss time forexample in Germany!

These areashavegainedlittleprofitfromthework design approach in accidentpreventionoverthe last years.

occupational traffic safety relevance
Most companies do not address traffic accidents since they happen outside company properties and they feel they have no influence.

Most state and insuranceagenciestreat all trafficaccidentsalikeas an errorofthedriveralone, thusignoringtheoccupationalcomponent, such as time pressure, lack ofsleep,increasedcommuting etc.

Ourdatawith 2000 small and medium sizedcompanysclearlyshowoccupational stress asthemainpredictor, followedbyexposition and distraction!

Illness (Infections, Backproblems, Cardiovascular) 40%

Accidents (Work) 10%

Psychological factors (Stress, etc.) 40%

Environment (Personal and Family Factors) 10%

Reasonsfor Time Loss in Germany

Study on 147 Mio. workers in the EU (2009):

  • 52% say, theyworkunderhigh time pressure.
  • 33% havenoinfluence on theirworkprocedures.
  • 27% havenoinfluence on theirworkrhythm and breaks
  • 45% havemonotonoustasks,
  • 44% havenojob-rotation,
  • 50% haveshort, repetitive time-relevant tasks
  • 16% reportlittleornosupport through leadership and colleagues

accidents are the result of various interacting factors

(road, vehicle)



(time pressure, leadership)


(riskinclination, experience)


(stress, weather, distraction)

Take homemessages

Third takehomemessage:

Psychological factorsarecurrently not addressedwith professional competence in mostcompanies!


Thereis a large numberofevaluated and successfulinterventions in Europe thatarebased on participation and haveproventoreduceaccidents and illnesses!

  • Participation in many modern areas of OSH is absolutely essential for success

Human centered work design is recognized by leadership as economically useful, in spite of contradicting behaviour

Ifwecoordinate, cooperate and participate in ourexpertises, wecan handle evencomplexsystems!
