Once, i had an entire day double booked (plus multiple hours before and after my working hours) and one hour in particular was quadruple booked. People were shouting at me all day about how I wasn't showing up to their meetings, but like... you could see my calendar when you put those appointments on there. That's kind of on you.
I got a talking to from my boss but they didn't reprimand me or anything, it was just "managing these kinds of things is an important part of the job". Eh. They did not pay me enough.
I hear ya.
I get 1-6 meetings in the same time slot, people don't care to check so I don't care to show.
I decide which meetings are important for actually moving stuff forward and screw the rest.
There's only ever one guy who complained to my boss...
I didn't show up for a meeting for a Friday 7pm, invite sent at like 4:58pm the same day for some inane and absolutely not urgent subject.
I saw that invite come in, chuckled, closed my laptop, went home and ignored it.
Later that night, the guy went nuts and CC'd everyone's bosses because he had wasted the full hour and obviously no one showed up to his meeting "even though I made sure to check everyone's calendar and everyone was available and you're all unprofessional".
I don't do emails notifications on phones as a rule unless you wanna pay my rate 24/7, but I had forgotten to do my time sheet so I was logged in doing that...
I dabble in a bit of passive aggressiveness in the face of corporate bullshit, so I finished my timesheet and hit propose new time... Sunday 3:21 am...
"Checked your calendar and it was available. Sorry for the inconvenience."
Closed my laptop and fucked off.
The guy went nuclear over several emails.
Sent a quick email to my boss "Just a heads-up, I think I angered someone by not attending their 7pm meeting they sent at 4:58pm and proposing an equally ridiculous time"
Never heard from the guy again and the next week he wasn't in the company AD anymore.
Probably went full tilt cookie monster in the coke jar or something.
At least in my case I get to click Accept or Decline in the Teams notification or in the mail. So I can decline them minutes after they tried to put it in my calendar.
That's what I do too - if it's a meeting I care about, I make the effort to suggest a different time. Otherwise, just decline. My calendar is visible and up to date, use the fucking scheduling assistant to tell you when I have time ffs.
I was a lowly bottom tier asshole at the time (doing senior work, just didn't get the title) so managers would just put shit on my calendar and assume i would clear everything for their pet project. Then they got upset with me when that didn't happen.
I'm not a programmer but I have at least one double booking every day. Some weeks look like a brick wall sideways (they seem to always overlap by a half hour for some reason).
First task on Monday morning... "Who is going to be pissed at me this week?" Go through and decline the least important meetings until I can get through my week without breaking the space-time continuum.
I used to do it Sunday night but decided fuck that - that's my time.
