Be sure to sort reviews by date. You'll notice that positive reviews typically come out shortly after a negative review. This is because after a negative review is posted, the marketing department goes to new employees and asks them to post a positive review to counter the negative one. The positive reviews are almost all actively solicited.
The owners care much more about profit than about employees.
High level employees keep leaving the company. A lot of them leave without even having another job, because they just can't work here anymore.
Employees are expected to work long hours under an overtime policy that shouldn't even be legal. Google fluctuating work week overtime before you accept a job here and decide whether you want to work for a company that uses it.
Employees are let go because of minor mistakes with no warning and no proof that the employee was even the one who made the mistake.
If they make a promise to you about anything, be sure to get it in writing, or they'll deny they said it.
There is a bullying mentality in the office, and if you aren't in the right clique, you can be targeted at any time.
Rules apply only to some employees, not all. Especially not to employees who have a family tie to the company. Some of them work hard and follow the rules and others are part of the problem.
