Interventions The intervention is a participative ergonomic program. The participative ergonomics apporoach is based on the active participation and strong commitment of the employer and employee in the process to identify (potential) risk factors in the workplace and to choose the most appropriate solutions for these risks. The program consists of six steps including a workplace observation, interviews and two meetings of one and five hours with (representatives of) workers and management from a department.
Primary outcome measure(s) The primary outcome measure is the incidence of back and/or neck pain in the year of follow-up, assessed by means of a postal questionnaire. In the baseline and follow-up questionnaires, data on the incidence of back and neck pain will be collected using an adapted version of the Nordic Questionnaire. Cases of back and/or neck pain will be defined as those workers who reported regular of prolonged back pain and/or neck pain in the previous 12 months.
Secondary outcome measure(s) Secondary outcome measures are:
1. Functional status
2. Pain intensity and sickness absence
3. Use of ergonomic measures

Data on sickness absence will be collected on the basis of company and occupational health services registers. With respect to the economic evaluation data related to direct and indirect costs (costs in paid and unpaid labor as a consequence of sick leave or disability) and quality of life will be collected
