I was was part of a startup that a number of Apple engineers went to; over half of our engineering org was from Apple, and were used to having that time off, our management chain was fine with it, and we just took it as part of our startup's culture.
The New CEO, a real sales guy, had different ideas. "I think that people can be really productive during that week." He was adamant that he wanted to see butts in seats, across the company. Engineers? Not special. (We were working until the early hours of the morning, nearly every day).
We were told by our director not to worry about it, and just not show up if we didn't want to. What was he going to do, fire half of his engineers?
Some people just don't get it.
