At a directors' meeting late in 2023, 11 out of the 12 board members were in favor of sending ultimatums to the staff to force them back.
I was the lone holdout -- and I never liked a work-from-home operating model for a business.
By the end of the meeting, all 12 board members agreed with me.
If you have a good staff, simply flipping a switch and changing the current status-quo can hurt your organization it a few different ways, so that desire to get where you want to be probably would be better achieved by a slow approach that encourages them back to the office, at least those who are amenable to this “change”. Then, for the holdouts, you have to be careful how to deal with those situations in order not to either lose your talent, or alienate those who have come back to the office and wonder why everyone isn't back.
Sounds like you have already covered this ground to me.
