Nothing here either. Though to be fair, my current employer hasn't really ever asked me to (not that I can remember) and the few occasions where I've worked more hours anyway, just because I really wanted to get something finished, have generally been noted and taken into account in bonuses.
Last company I worked I pretty much had to work every hour I was awake, and several where I probably wasn't. They barely paid me for the contracted hours - though the fridge was reasonably well stocked (too well, in fact, if you ask my waistline).
Oh, as the post a few above says - I do get time off in exchange for working on holidays or weekends if necessary. Plus any trips are mostly expenses-paid, so I'd be eating in expensive restaurants on this TGS trip... if it was a work thing rather than a holiday!
