Any recording that breaches the section is off limits to the employer for every purpose: not for discipline, not for investigations, not for litigation, not for security review. The section applies to private and public employers alike, except the federal government. The practical control is a rule that any footage or audio discovered to come from a protected room is quarantined and destroyed, not viewed or relied on.
The graph holds this control, the 0 it maps to, and the evidence behind each claim, over MCP and REST.
