It’s not a license to engage in historical revisionism. Like the myth of the clean wehrmacht, the notion that Hitler didn’t have the broad support of the majority of German citizens is an attempt to deny the culpability of everyday Germans from the war crimes they were collectively responsible for in WW2.
Only takes one or two employees to pretend to have heat stroke/exhaustion and get a work sponsored trip to the hospital to force a change in the working environment.
Really would be safer for everyone to have someone pretend rather than wait until someone actually has one.
