I have a senior coworker who's not my boss (in her early 60s), but she acts like she is because she has the most experience. This is a salaried position, and she loves to work on weekends. She spends so much hours working and wants everyone to work like how she does even when there's no urgent deadlines.
She kept giving my 2 other coworkers (we are all young and less experienced) assignments to practice on weekends so we could be more knowledgeable in our field. I did them for 2 weekends and stopped because they weren't expected to be done. She got mad because I stopped doing and asked me in a serious face as to why I stopped taking her seriously and doing my assignments. I told I had plans, and she kept interrogating me. I told her that I had schedule to have s3x with my fwb and asked her if she wanted to know where it was at because LA is spread out and he lived kind of far. I told her she could come watch. Then she told me it was too much information. I told her to stop acting like my boss. She finally stopped talking to me.
Then she went to my boss saying that I was inappropriate to share such personal information. My boss called and I told him that she kept asking me what I was doing when I already told her it was a personal appointment, so I had to tell the truth. My boss was like “okay.”
