The Guidelines give as an example of prohibited processing an employer using recordings of a demonstration to identify strikers: inferring participation in industrial action from footage is special category processing (political opinion, trade union activity) that the employer has no ground for.
This control maps to 2 controls across 1 other frameworks. If you already hold one of them, the evidence you collected for it is the starting point here rather than new work.
Every mapping shown was judged rather than inferred from wording similarity, and the ones that failed review are published too. See the coverage reports and what was rejected.
The graph holds this control, the 2 it maps to, and the evidence behind each claim, over MCP and REST.
