Seriously, nobody should EVER work for Cheery English!!! They don't specialise in kids education at all, they only specialise in lying to all members of staff (chinese and foreign), sucking the life out of them all, not paying them correctly, changing contracts/pay/schedules last minute and then pretending not to understand when you are annoyed. I've seen staff get fired simply because they disagreed with something ridiculous.
They look nice and helpful when you first walk into their office, but underneath that shiny surface, they are blood sucking leaches. STAY AWAY!! No matter how much money they offer you, no matter how nice they seem, you will probably get fired anyway...
