The vacation policy is TERRIBLE! Employees can "take as much vacation as you want" with manager approval. There is no accrued time off. However, if you aren't hitting your targets, it is highly implied / frowned upon to take vacation. So not only do you give up what would be paid vacation, but you work through it. If Sony doesn't want to accrue years of vacation time, then it should at least pay employees for vacation hours earned at the end of each ear.
Sony keeps bad managers in place far too long.
