CEOs frustrated that workers aren’t coming into the office more often are trying a new tactic: tying in-person attendance directly to higher pay.

At least one big law firm has explicitly linked office presence to employee bonuses.

At other companies, the connection is more tacit. Google recently said it would use face time as a factor in performance reviews; executives didn’t have to spell out that these ratings influence compensation. Nor did IBM Chief Executive Officer Arvind Krishna need to explain what he meant when he said “your career does suffer” if you work remotely; if it’s harder to get a promotion, it’s naturally going to be harder to get a raise.
