I like her style. I wouldn't be surprised if the appointment was for an interview, which she's now received a formal offer for.
I accrued many hours of overtime one year and got royally fucked over by being refused TOIL, told to put a claim in and then informed that, as my contract said TOIL, I wouldn't be paid for it. And that it was too late for TOIL. My contract then got changed to say I would be paid for all overtime, but only if approved in writing ten days in advance. A letter accompanied this saying that, to add to that, I was not to request the time, the boss would inform me if they wished me to work overtime two weeks in advance. The general feel of the letter was Know Your Place and attempted to be very threatening in tone.
So, when particular things that were known about many months in advance came up, I waited for the instruction request to work 18 hour days. It never came.
I went home instead. Seems that it was assumed I'd work the hours anyway, which would have put me in the position that I had not been told to, so would be doing them for free.
The fallout was quite spectacular, by all accounts. I just said when hauled in for it that I was a little confused how I could stay when [holds up contract and letter] x sent me these on [date] instructing me that if I were to do so without specific instructions with x notice and written approval, it would be regarded as Misconduct.
They never tried that one on me again. As it was, sometimes I would agree if asked, to take it as TOIL, sometimes there would be a set payment offered and I took some of them. They were slightly peeved when I declined working 7 days a week + 3-6 hours extra a day for 2 months, though. Wasn't 'very helpful or teamwork', apparently. It wasn't in keeping with the European Working Time Directive either.
Sometimes (if you can afford to take the risk, ie, have employment rights or a new job), it's good to make a stand. Especially for the benefit of others seeing you aren't taking that level of shit.
