-The management doesn't care about you. They see you as a way to drive business. Beyond that you are worthless to them.
-They make up excuses to delay your promotion (money-saving experts)
-The job itself is 90% cold calling
-When you decide to leave they forbid you from telling anyone (less likely for others to leave)
-Company culture based around fear
-High staff turnover
-They know the company is TERRIBLE, but will try to convince you everywhere is like this.
-Company values are a joke. We don't care for quality. Only money.
-Whenever you'll have a complaint they'll blame it on the "business-model"
There is plenty more that is wrong. Too long to list.
