I have a colleague who copies my manager into every email they send to me. No backstory of issues between us, had a good working relationship over the past year since I started working there. The emails are not particularly contentious, sometimes it's just a "can you attend this meeting?" for example. Would you find this passive aggressive? It's starting to really grate on me and i feel hugely undermined. No one else does this. Am I overreacting that this is really getting to me now? I plan to raise it with the person but I just wanted some perspectives first as I'm not sure if this is my issue or whether this would irritate others too!
