Looks like Marissa Mayer banned telecommuting at Yahoo! armed with data from related to how employees were not logging in via the company’s VPN.

Kudos to Mayer for using data to make her decision, but data alone should never set company policy. I can’t help but wonder if those employees legitimately working while not at Yahoo! headquarters now have to pay for the sins of slackers. And, as I’ve seen first-hand in my career, slackers will always find a way to slack off. That’s what they do.

That goes double in an era of BYOD and constant connectivity.

Something tells me that Mayer will regret her decision.
