Common management tricks in private language schools in Japan, South Korea and Taiwan are: * not enroll you into mandatory health insurance but instead sell you private accident insurance * illegal deductions from your pay cheque such as over taxing * over charge for rental of a company apartment * charge for an illegal cleaning fee when moving out of company's apartment * hire you at part-time hours so you don't qualify for health insurance * not issuing a "statement of release" (n/a to Taiwan)
