While I was there, the owner forgot to pay the company's bills on time, paychecks bounced at least once, and he left on vacation without telling everyone during our busiest week of the summer. He will go weeks without contacting you, only to call you and berate you for an hour about something he clearly doesn't understand. If you do have the misfortune of working with him, make sure any agreement you have with him is on paper and signed and refuse to do any extra work outside of a written agreement. The "bonus" system for lead teachers, where a third of your pay is withheld until you finish the class, is exploitative and difficult to incorporate into your personal budget.
