I was talking to my wife the other day, my company would have to basically double my salary to get me to go into the office. Work life balance during WFH is actually balanced, I actually like my job and the company I'm at, I like the people I work with, I'm more productive and less distracted at home, I get to spend time with my daughter and take care of her, there's really no downside to WFH for employees that want to WFH.
Working in the office? In addition to the normal costs (clothes, food, transportation, etc), losing 2-3 hours per day commuting, paying for childcare or having my wife not work, getting a second car or my wife not having a way to get to work or take our daughter to appointments, and plenty of other inconveniences and big changes.
Working in an office is an outdated concept for most office jobs now. 100% of my job can and is done remote, even if I had colleagues in my office, a quick teams call or message is just as easy as pulling them away from their work with a question in person. It would take a very very large raise to get me to go into an office, and I would likely be looking for a remote job asap using that newly inflated salary.
