Obviously we don't all have the option to bail at any time and find other work, but if this is the kind of culture you're seeing as normal, I feel very sorry for you.
Anyone in this position should -- for their own good -- at least attempt to take a longer view and see if they have options that don't involve constantly sleuthing to narrow down your job's expiration date. Unless you actually like living like this... in which case, hey, it takes all kinds. ;)
