Trust? If the features are being shipped there really isn’t much trust required. You know after a week of that employee is delivering. Being in the office does not guarantee a single minute of additional productivity. In fact, I get more done in 2 hours working remote than I do at a typical day on-site.
Making people work on site for roles that don’t actually need to be – that’s just nonsense. The only thing I care about is shipping. I don’t care about eating lunch with the team, I don’t care about the idle chit chat. I certainly don’t need to be sitting in a conference room looking a a computer projector during sprint planning when I could just as easily be seeing that same screen and listening to the same conversation sitting in my office at home. When I work with the team, RARELY does it require interpretive dance to get a point across. Even white boarding can be just as easy remotely.
If you don’t trust employees enough to be remote, then you shouldn’t hire them to work in the office either.
Hardware engineering or other physical product-based businesses, I get it, remote usually doesn’t work. But for writing code, sales, marketing? Not a single reason not to be remote except if are working on something that requires a triple-lockdown environment and is highly secret. Very few companies have that level of absolute secrecy as a requirement – but even then, there have been known to be remote people even on those types of teams.
