National Preventive Mechanism this type of explanation, even if attributable to the prevailing national legal situation, contradicts Article 27 of the CRPD. Workshops, but also therapy facilities for drug addicts, cooperate frequently with private customers and make a profit. The clients do not usually benefit from this. Persons with disabilities rightfully feel exploited when they are guided and instructed in projects to clean buildings belonging to operator institutions or facilities, or to assume other operational tasks without receiving a monetary benefit and being allowed to save their earnings. For the NPM it is beyond any doubt that new models to reduce the artificial barriers to professional training, to further training and to education must be developed in terms of inclusive support structures for the promotion of occupational participation. It must be guaranteed that persons with disabilities gradually find their way into working life by means of income compensation while at the same time preserving their greatest possible freedom of choice. According to the work programme 2013-2018 of the Federal Government, the autonomous social security for activities in workshops should be strengthened, the artificial barriers between the first and third employment market removed and the transfer of workers from workshops to the first employment market pushed. This has not taken place to date. Missing possibilities for complaints Observations made by the commissions indicate that clients with learning difficulties or mental illnesses are often afraid to complain. Common reasons for this are fear of possible negative consequences or aversion to confrontation. This becomes clear in interviews with the commissions. There must however be a possibility for all clients to complain anonymously. It is the responsibility of the management to make it clear to staff on all levels, that anonymous complaints and suggestions are also desired and will be taken seriously. 5.4.2 Causes and forms of measures that restrict freedom, and violence Although modern pedagogics for persons with disabilities is strongly orientated towards self-determination, empowerment and a life according to the normalisation principle, measures that restrict freedom are carried out in residential facilities and workshops as well. Structural barriers, but also the use of mechanical, electronic or medication-based restrictions of freedom, are repeatedly thematised in commission reports. Inadequate documentation, formal and notification violations 156 The documentation of the restriction of freedom is often inadequate. The legally stipulated notification of the representative(s) of the residents is often neglected or of different quality. Some of the notifications are completed with care and are traceable; in some cases there is no mention of more sparing measures. The signatures of prescribing doctors for medication-based measures
