The work environment:
First of all, most of the cubicles are so small that you can't even spread out your papers to work. The open office floor plan was so noisy. It was so hard to concentrate on your work with people talking on the phone or to each other all around you.
Work-life balance:
You should not expect a work-life balance. Expect to work every weekend during the busy season. Management did not bring in seasonal staff to help with the increased workload during the tax season. Instead, management takes advantage of the fact that you're salaried and they don't have to pay you overtime.
Quantity vs. Quality:
Make no mistake about it - the quality of work is not a priority. It's all about production. You will not be able to keep up with the workload if you prioritize quality. If you can't work as many accounts as they've assigned to you, you will eventually be fired.
Ethics:
Managers at my office were the most unethical people I've ever worked with. Management required staff to produce fraudulent tax documents. Management signed these fraudulent tax documents and underreported asset values if they thought they could get away with it in states that don't audit.
Management also made staff manipulate time entries so that they don't have to write off time. For example, if they sign-up a client with a lot of accounts on a flat fee basis - you will be expected to charge time up to the flat fee. You will be told to code any time it takes to work the accounts beyond that as admin, training, etc so that the manager doesn't get in trouble for spending more time on account than they can bill for.
