While I understand the need for just a few managers, I have noticed quite a few will remove one without so much as a 'see ya' - I understand there is a need for efficiency.
Yet there is a protocol for opening a profile that is in need of merging/cleaning and it is done to allow a manager to deal with the issues on the page. Which can take weeks to 'clear up' - but it is done out of courtesy and the "one tree'' collaboration that is central to WikiTree.
There is also a protocol for removing people as profile managers:
Remove extra managers
No profile should have more than a half-dozen managers. One or two is usually enough.
It's a good idea to contact Profile Managers if you're removing them and this might come as a surprise. It could easily offend and upset new users who aren't familiar with how WikiTree works. This doesn't mean it shouldn't be done. It just means we need to be sensitive.

There are a couple of supervisors that seem to have forgotten this.
I came to WikiTree Because of the collaborative effort - yet when one person takes it upon self to remove all other managers leaving just themself? That is a bit off-putting.
