Work conversations secretly recorded

My co-worker and I feel that our boss is secretly recording our conversations. During the day, he will come up and make comments about things we were very quietly discussing. Mind you, he is about 6 walls, and 60 feet away. Is it illegal for him to record us without our consent?
