Nothing. The lowest bidder will get the job.
So many companies are now facing the reality that they can toss their employees a few dollars more to stay home and it costs the employer less money in the long run, as they don't have a physical plant to maintain. Think about it. No heat, no lights, no I.T. staff to maintain no network. No desktop workstations. No restrooms. No office to clean.
My wife works for a financial institution. She's been working from home since March. The only time she goes in is if they need a physical thing done, like loading money on plastic cards. That only happens 1 day every few weeks. I think she's had to go in less than 10 times in 9 months. She has a card table set up in the corner of the living room. That's her office. They gave her a laptop and a 2nd monitor, a keyboard and a mouse. Her boss said they've been more productive than ever, and doubts they'll go back to working in the office anytime in the foreseeable future. No reason to.
I suspect they are more productive, because they aren't right next to each other gabbing all day. Everything is done via web calls and zoom meetings.
She loved it this summer. At 12:01 each day she was out in our pool for 55 minutes. Back to work at 12:59.All fall she took walks at lunch. Now that it's cold out, she rides her elliptical machine at lunch. She has no reason to go back.
So to answer your question, office work is virtual. Doesn't matter where you live as long as you have good connectivity.
