Prisoners are entitled to appropriate work matching their capacity, aptitude and skills.
Under section 44 StVG prisoners are obliged to work. Work must be assigned according to their physical capacity, aptitude and skills and must be appropriate. This means that physically excessive or entirely unrelated tasks can in principle be challenged. The facility management has discretion in assignment but is bound by the requirement of appropriateness.
What to do now: First, document vocational training, physical condition and skills in writing and submit this to the facility management. Second, where the assignment is clearly inappropriate, raise written objections and request a review. Third, inform counsel of the work situation where an appeal is being considered.
