The employer should monitor only in ways workers would reasonably expect and that do not cause unjustified adverse effects; a DPIA, required in some cases and advisable in all, helps show this. The ICO's examples: CCTV in changing rooms to catch thieves is unfair (a camera on the door outside, signed and time-limited, is not), and case-management productivity reports that ignore reasonable adjustments for work done outside the system are unfair and inadequate.
This control maps to 1 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 1 it maps to, and the evidence behind each claim, over MCP and REST.
