I am one of the "hold over" employees.
And as I said aboveb when HR is contacted they act surprised and they say that it'll be taken care of, but it continues. I'd suspect from that that HR is complicit in it.
That's why I asked above if it would be legal to videotape WITHOUT AUDIO in order to collect proof that this is rampant among certain employees, and then take that proof to the proper authorities, whoever they may be.
