Boss forces fully remote company to return to the office 5 days a week, while he works from home on Fridays without letting the rest of his team do the same: 'Leadership roles have different requirements.'

He should hold himself to the same standards he holds everyone else to. 

It can be really hard to convince employees that they "need" to go into the office when they've spent years working from home. If the company is doing well and work is mostly conducted independently or via Zoom, why should employees have to return to the office? It's not like they're leaving profit on the table from not being in the same room as their coworkers five days a week. After all, it's probably cheaper for all employees to work from home than to rent expensive office space. 

Depending on the place you're at in your career, you might desire to go into the office to build stronger connections with your coworkers. If your tasks involve a lot of collaboration with others, it's going to be much more difficult to do so over video chat. If you're young and you really want to build relationships with your colleagues, working in-office might be the best option for you. But if you're comfortable with staying in your current position and don't care about climbing the corporate ladder, you probably wouldn't be motivated to spend the money to commute to the office every day. If you're later in your career, gathering around the water cooler might not feel like it's worth it, and you'd probably be right about that. The unfortunate truth is that unless you have an undeniable talent that makes you highly sought after as an employee, you probably won't have a choice about whether to work in the office or from home.
