That scenario used to bother me at work; years ago I realized it presented a great opportunity to reduce my workload/hours. Nobody can complain when you do the bare minimum - and it is still far more than the female “office toys” or the lonely men in positions of authority pursuing them. In fact, they don’t even seem to notice; their absurd games can be beneficial for all involved; the general lowering of standards provides a much better work/life balance.
But when it's pointed out that it's actually the man who is screwing employees over in return for sexual favors, it's actually a good thing. Talk about putting lipstick on a pig.
