If you have been there for over 5 years wait for the payout (if you can) otherwise get out and ensure you are paid for the work you do. I was at Sh*t Show & Calamity for over 5 years and got paid.
If you are new and just starting out a great place to learn how not to do things, get experience and then move on to somewhere better (which is pretty much anywhere else..)
Don't do as some of my colleagues did (and still do..) stay and take sh*t daily from management who have no emotional intelligence, technical competence and regard for more than their next project and have a daily dread when logging on every Monday to more of the same.
