I manage 11 employees on three different teams. 4 in the Twin Cities where our HQ is, 1 in Duluth, 1 in Missouri, 1 in Florida, 2 in Poland, and 2 in Australia.
I go into the office about 3 days per week to get away from home and when the weather is good I bike the 10 miles each direction to get my exercise. But I don't go in because of the "work experience". My desk, monitors, etc. and the amenities at home are just as good or even better than what I have in the office. Aside from some socializing with a small group of regulars, I don't really get much advantage of collaboration by going in. My building is the 3rd largest on campus and seats about 500 people, but we only get between 20-40 total on any given day because everyone was given the option to work from home even after the pandemic is over.
I actually like not having my employees there since they are so spread out around the globe. It doesn't make sense for me to have a team meeting with one employee in person and the others online. I have regular individual meetings with each of them and regular team meetings to make sure that we all establish relationships. And it is actually pretty impressive how well that works when you've got people that turn their cameras on for those calls. Most of these people I've never met in person but can have a decent chat about how things are going with their families, hobbies, etc. before jumping into work discussions. We had a fellow manager that joined the company a year ago that I never met in person but talked to a lot because we worked on projects together. He just left the company but I had lunch with him his last week. We were able to interact like colleagues rather than strangers when meeting in person for the first time because of the video calls.
The people that are going to suffer is the managers that don't know how to adapt to not watching over their employees' shoulders all day and the extroverts that need to be talking to a lot of people. There is something to be said that productivity is lower for employees working from home, not for everyone but it is enough to be measurable for many jobs. But the problem is that this is the new world and if we don't adapt then we will lose good people and see even lower productivity from having open positions or hiring less experienced employees as replacements.
