Do you folks have a constant "culture switching" in workplace? by switching i mean things like standup time , leaving time , lunch time etc getting changed every few days?

I feel like being part of team that is run by a dictator ever since our tech lead changed.

earlier we used to have 11 am standup, now out of blue she decided it will be on 9.30.
Its weird because most of the team can't reach office before 10am on WFO days and I personally ma having my breakfast with laptop open till 11 on WFH day.
I mean it could look bad if I was a construction worker getting paid by the hour, but am a fucking developer who can write code on his own time and only my work and timelines should matter.

same thing about leaving office. there is no official time to leave but i have to travel 2 hours so i usually leave at 5. i usually compensate this with working till 8 -8.30 on a wfh day but now sudden 1.5 hour meetings are becoming so much more common.

Another thing about leaves. earlier we could take leaves if we had some of our 22+ paid leaves remaining.
We would just need to inform to our manager and 99% of time he would instantly approve.
Now it feels like giving a request to government office. TL would not approve until the very last day. and if the leave falls in a month where other people are on leave as well, it might not get approved at all .
mind you, our team is quite decent at 5 android devs, 2 ios devs and 2 backend devs. i am an androdmid dev and i couldn't het a leave even if all 4 other devs are present on a day but an ios dev is not present, which I don't understand why?

weird cultural shift from "we have a relaxing environment and only focus on achieving targets" to "you do as we say, there are no team decision and votes"
