May my employer place cameras in toilets or changing rooms?

Cameras in employee toilets, changing rooms, showers = four-layer prohibited. Sr Art. 139f criminalises covert image recording in private place — max 6 months prison. GDPR Art. 9: body images in intimate space = special category data. Dutch Occupational Safety Act Art. 3: employer must guarantee safe + dignified workplace. ECHR Art. 8: private life inviolable. When IS it still allowed (theoretically)? Only on specific concrete incident — e.g. repeated proven theft in locker-area — with DPIA, only temporarily, only locker zone (NOT shower/toilet itself), only after works council consent. In practice: AP almost always rejects. On suspicion: immediate AP complaint + police report (Sr 139f) + Labour Inspectorate (Dutch IGSZW) + Social Affairs Inspection. Damages claim Art. 82 GDPR: typically €5,000-€25,000 for non-material damage. Plus possible summary dismissal for employee responding to camera. Real cases: 2024 production company with covert changing-room camera investigated by AP — €350k fine + director dismissed + civil claims.
