Rampant nepotism
Horrible on the job training program
Poor wages in comparison to other companies
Poor company outlook
Bigoted management (Certain coworkers have noted that inexperienced colleagues are often promoted ahead of them)
No opportunities for advancement
Inept management
Suspicious activity (occasionally something questionable would take place. When the people you're supposed to report these activities to are the ones that carry them out, what do you do?)
If you're reading this in anticipation of applying for a Tax or Payroll position, be especially cautious. The workflow is absurd.
Sloppy practices overall. That extends to promotions, upper management, business flow, company direction, and all major corporate functions.
If you NEED a job, by all means apply. As of now, this isn't a company you should build a life around. Take as much as you can and move on.
