      Timely pay can't compensate for poor management and no growth

      Business outlook

      Pros

      Paycheck is on time, never late.

      Cons

      Extremely Low Pay. Almost Non Existent Annual Raises - doesn't even keep up with inflation/cost of living increases. No career growth. No promotions. Management doesn't resolve issues. Expected to do more than your job duties with no extra pay. Overtime system extremely skewed towards the company. Promised many things but never delivered even after working there for years. Management doesn't listen to customer complaints. Management doesn't listen to employees or reward anyone for going above and beyond. Lazy coworkers/management. Short staffed.
