Work issues - how to act?!

[Goular78]

Has anyone been in a situation where a more senior colleague has been acting hot and cold with you for no apparent reason?
I can’t ignore him as they are more senior and we must work on projects together.
I get that people are busy and stressed and not up for a chat always, but to be sharing personal info one day and then not even saying hi the next is plain odd.
I do find the behaviour disturbing as you never know where you stand with him.
I have tried to avoid him as much as I can, but now he’s cold in the office but will call me when I am wfh for a chat, and he’s like a different person, all happy and chatty.
I don’t know why this bothers me this much - he’s more senior and has more influence at work so I do have to get on with him.

Any advice?

My LM can be like this sometimes. Some days they're overly chatty, sharing personal information and happy to chat and other days, I feel like I'm intruding on their day by doing my job.

I just take it as it comes now and assume that on the 'off' days, there may be other factors to blame.

I think you’re reading way too much into this person’s behavior. Just treat them the same regardless. It’s very unlikely to be anything about you when they’re running cold. And honestly not being overly chatty or too busy to say hi is not really cold.
