For you. I've done it for 8 years and I love it. I'm on the south coast and my office is in North Shields. I'm there twice a year, the rest of the time I'm home and I don't see people that often. For me it works, and my mental health is better because I'm not constantly surrounded by people I don't like. Where home working permanently is an issue, is that you lose social skills. I've forgotten how to have a normal conversation with someone, and the silences are painful.
I think you'll see a bigger transformation to home working and collaborative office spaces than you would if Covid had never happened, but it was always going that way. As long as businesses offer people the choice of office or home, then thats up to the employee to decide whats best for them. It'll never be all or nothing because not every industry can work that way.
One thing I am keen to see is how taxation will change for employees who are home based. There is a worry that business will try and lowball staff because they don't have all these extra costs anymore, but my argument to that has always been you hire someone based on their skills, not how far their commute is. The company is already saving money by having me work from home because I use my own utilities, they don't have to buy office equipment or fit out an office.
Hell, they could even just outsource meeting spaces to a third party, you as an employee book them, and the company is charged for usage time.
