I strongly encourage employers mandating a return to office in NYC to publicly announce it. Makes it straightforward to identify where to source new remote talent from.
Have a friend in HR at a fortune 500 company. He said that early on, they were not sure on what the work from home rules would be and they found that applicants were simply ghosting them when they found that it wasn't a set in stone policy yet. They are trying to hire a lot of tech talent and so they had to officially declare that people would have extensive work from home privileges if they were going to get anywhere close to their hiring goals.
