We recently got a new CEO and he took away everyone's ability to work remotely, including that of my most productive team member. As you can guess, everyone's productivity has dropped considerably, but nothing hurts more than one engineer's productivity.
To give you an idea of what's at stake here: my all-star engineer has gone from performing at the rate of roughly 2x an entire team of 6 combined, to what's average for a single individual on the team at his seniority level. As you can imagine, everything is now going very slowly and it will be impossible to meet our targets.
I also recently find out he's actively interviewing with other companies and really want to retain him, but I'm afraid no amount of incentives other than working from home will help. As for the catch: this engineer is disabled and HR refuses to accommodate Work From Home (WFH) as it would present an "undue burden to the company." We all use Zoom, Slack and Email without a problem, and WFH is definitely seamlessly integrated into our business process.
Unfortunately, with our "no WFH policy," we've since lost a considerable amount of talent and continue to bleed dry of talent. It used to be that I could have my engineer pick up the slack of other team members, and have him finish a lot of additional work in the sprint queue, but now we're barely getting anything done.
I should also add: it's not easy to replace people in this field. This is Information Security, and we've been looking for team members for years but qualified talent keeps turning us down repeatedly.
Update: He left yesterday, citing lack of handicap-accessible doors. There's no way for him to reliably get in and out of the bathroom without help at work, park his handicap van or open any doors easily. HR refused to accommodate his work from home request and doctor's note, and forced him to take a medical leave, so he just quit.
