Have worked happily within a team of 8 colleagues for over 10 years. We have always been treated equally and fairly by our male boss. Lately we've noticed that one of us has been receiving favourable treatment over the rest of us e.g. overtime for non-essential trips, first dibs on her timetable. She has also boasted that they go out every weekend. He's married, she's not and has admitted that she's fancied him since she started. She also seems to know personal info about the rest of us, things we told him in confidence. Can't discuss with his deputy as she says "How high?" when he tells her to jump.
