AIBU to feel uncomfortable with corrective feedback in a hybrid role?

[Flowerlotuss]

Looking for outside perspective on a workplace situation.
I work in a hybrid role and mostly WFH, with occasional office days. A line manager I don’t report to daily has a very corrective communication style when it comes to small process issues (e.g. WFH/office flexibility, timing, etc.).
Recently I went into the office, then left at lunchtime to continue working from home (all office tasks had been completed). I was told I should have asked in advance rather than informed after, and it was raised quite formally. I’ve had similar experiences before where feedback felt quite strong or disproportionate to the issue.
I don’t have an issue with following expectations, but I do find the tone and escalation quite uncomfortable.
Is this a normal hybrid workplace management style, or am I overreacting to tone?

Well, I’m not sure, I could start trying that. But yeah, I think maybe the issue is there’s no explicit rules or anything in writing.

Can you get both line managers to agree on the rules for hybrid working?

It is not in anyone's interests for the managers or reports to have such a fluid situation and for people to find they have tripped up when actually the rules are not clear and/or not consistently enforced.

Yes of course. I agree completely. I think perhaps what I’m getting at is her communication style - it feels like any interaction is an opportunity to assert/reprimand - I’m not her subordinate, we’re colleagues - there’s a difference between saying “hey, just a quick heads up before you continue from home to keep track of office presence” as opposed to “where are you? Blah blah” there’s just no decorum whatsoever. I’m not expecting sugar coating or anything but just as I maintain respectful communication with my colleagues I expect the same from her (and anyone else).

Yes, I think I might raise this in another team meeting.
