I wanted to share my experience in Shenzhen because it might be helpful when choosing a school. I worked for Meten at the Hongfa location.
Lets start with the pros:
I loved teaching and I loved the students. I lost more than 26 pounds while I was there. Ok that's about it.
So here's the cons:
I was never given my release letter, reference letter, or work permit cancellation at the end of my contract. Even after I gave reminders several times. I also never got my bonus even though I met the requirements and on a couple occasions they didn't pay me for overtime. Sometimes payday was delayed too. Also, texting me at 11:30 pm to change my schedule or just not telling me at all. Doing 4 to 5 ishows a week when we're only required to do 2. Some staff refused to help students after enrolling them. Unpaid mandatory meetings on my days off and always denying my vacation requests. No A/C in the building half the time. The HT would never say thank you for all your hard work etc., etc., etc. A couple of the FT's broke their contracts and left early. I've seen some of the LT's work just a few days or a week and quit. It has a high turnover rate. That raises a red flag. Just bad bosses. It could be a great school but it's not.
And some additional comments:
By the end we were all just going through the motions. There was always a dark cloud over our heads. It was hard to be positive and optimistic. I'd hope it's only the location I was at. Is every location this way? Maybe that's the business culture.
Choosing the right school will make or break your experience in China so think twice.
