There is someone I have to work together and we both work remotely. I'm a data scientist and he is a product manager. This person appears to be always busy. His Slack status is either on a huddle or on a meeting. He is probably having more than 10 meetings a day lol. When I want to talk about something with him, he asks me to set a meeting on calendar at weird times like 2 days later, but we can actually solve the problem right at that time in couple minutes.
Normally I don't give a shit, but I don't like his attitude recently. He says stuff like "I'm focused", "Don't be distractive" bla bla. He also said that "You are not working at all" because I'm managing my time in a more flexible way. I think he will try to get rid of me soon. I have no idea how to deal with this. Does anyone had to work with this type of person before?
