The whole point of 1on1s and retrospectives is to optimize your work. If you literally only have these two meetings per week and you still find that unreasonably disruptive, then you could discuss dropping them to once a fortnight. If you still find those two meetings per fortnight unreasonably disruptive, and you really get absolutely zero benefit from them whatsoever, perhaps you should be working as an independent contractor and not a salaried employeee with a team of colleagues and a manager.
I do understand where you're coming from. I have had several direct reports who never had anything at all to say in their 1on1s, who had no interest in setting goals, no interest in advancing in the company, no interest in improving their workflow, who honestly just wanted to sit down, do the work, get paid, go home. That's fine, and it's useful to have some people on the team who want to work that way, but they really are a minority of people I have worked with in "normal" company environments. To be frank, I would prefer to work that way myself, but that's not really how most companies operate, because most companies are geared for growth, so it's not enough to just stay at the same level of productivity forever. The goal for most companies is to continuously improve and increase their output, forever. This is why most companies see value in having these meetings, because they are a way to focus employees on becoming ever more productive.
That escalated quickly.
Good points, though you're talking past each other a bit. (I'm not disagreeing about 121s' value nor flow's unschedulability.)
You should try it!
If I have a standup at 10am every day, this guarantees that I'm not going to ever get anything substantial done before 10am. A 3pm weekly meeting can mostly destroy my ability to get in to deep work for that afternoon.
I don't "schedule" deep work, it is a thing that happens as a combination of what needs to be done, the time available, minor tasks, and interruptions.
Daily and weekly meetings significantly reduce the surface area available for these things to happen, and often serve as a source of boredom and frustration, being in a room with people who obviously don't have anything to say, saying words because they're supposed to.
