Low Pay (though this is typical for publishing)
They don't fire bad bosses, even if they're incompetent, if they're "in" with the right people
Overworked staff leads to burnout
They're weirdly cheap about random things: i.e. They "close" the office for the week after Christmas but you have to either use your own vacation time or take the time unpaid. Most other publishers pay their employees for this time off. Plus they try to convince you that this is a good thing by putting a positive spin on it - 'Hey we're giving you time off at the holidays"
