No decision without a human
An employee has the right not to be subject to a decision based solely on automated processing that significantly affects them [1]. A promotion, an appraisal or a dismissal should therefore rest with a person who genuinely weighs the outcome.
The works council
For a scheme on the appointment, dismissal or promotion policy and for a scheme on staff appraisal you need the consent of the works council [2] [3] [4]. If you introduce AI that changes such a scheme, put it to the works council.
From 2027: high-risk
AI for decisions on promotion or termination and for evaluating performance and behaviour is on the high-risk list [5], with duties from 2 December 2027 [6]. Before you use such a system, you inform the workers' representatives and the workers concerned [7].
