Okay her “regularly scheduled time” ie she was not “on the clock”.
Have you not gone to work when you were “not on the clock”?
I know I have.
More often, and for longer, and under worse circumstances than you likely imagine.
I still dress appropriately ... note that "appropriately" differs according to whether I am in my office or in some godforsaken pesthole in the middle of nowhere. In either case, I don't forget that I'm representing my employer.
