Well, we really can't say when someone should be sleeping. People have different sleep patterns, and there is no enforcement (nor should there be) of when people are allowed to be awake and on the computer.

However, this should be an easy one for the company to look at and follow up on if they wanted. The evidence should all be there on the computer. I suppose, "If they wanted," is the key phrase.

Perhaps serious OTP recycle? I'm not sure why the company and the union don't do a LOA about not being able to reuse that, I'd think they'd both agree.
