I used to work for MKC and are returning soon(as have a few others) and compared to many other schools out there MKC is easy to work for. Not sure what Canucki wants in order to keep the classrooms "comfortable". A foot massage every day!
As for "huge amounts" of money being taken out then if you consider a few RMB for being late huge amounts then maybe showing up to work on time might save that "huge amount"!! Every company and business has rules that you have to work by and realistically MKC doesn't have the strictest ones out there! As R said this is a job teaching not having parties and its not always all about the teacher comfort!
Principals - I found them ok to work with.
