Surf the net at my business or schedule a personal appointment on my time without prior approval and expect to get paid for it...and you are gone. I am continually astounded at how many people think they should be paid to screw around or take care of personal business. Money is very hard to make in any economy, and employees who aren't productive aren't worth paying.
To the OP, that wasn't directed at your wife. She may well be an exemplary employee and her boss may well have a problem with her not based on her performance. There was a sense from some of the responses you got that employers owed employees free time while they are on the clock, and that crap pisses me off.
