I've been thinking a lot about hiring recently. Friends and acquaintances often tell insane stories about their workplaces, and inevitably the problems all stem from poor hiring. The specific request in TFA is insane and shouldn't be entertained. This doesn't mean the employee in question is bad, but, in general, when you entertain requests like this you're bound to pick up a few bad eggs. When you build a team, you want to ensure that everyone has the right mindset. This means people with little ego who are willing to put aside their personal differences to do what's best for the team. Starting your employment with a bizarre religious exemption to using Windows does not illustrate that in the least.<p>There is also the related question about why the company needs <i>this</i> employee. What I've seen is that such red flags often come up in hiring. Good managers recognize that there is a potential culture fit and pass without losing any sleep. Bad managers, those who obsessed with increasing their headcount, are willing to ignore such signal. They're willing to sacrifice the quality of the team, its output, and the company at large for their own personal gain.
