I've been having this on going fight with my government high school. Each year they write in the contracts that the teacher's are only entitled to 15 days sick leave a year. I've tried explaining that Thai law states that all employee's are entitled to 30 days a year. The response has been that Thai government employees are not entitled to 30 days. The head of the department feels that its not fair that the foreign teachers should receive a superior benefit vs. the Thai teachers. Today in Thaivisa, I see a lawyer stating that the 15 day sick leave in a teacher's contract is an illegal clause and doesn't overrule Thai law. Sick leave from an International School - Ask the Lawyer - Thailand Forum I'm not asking for a greater benefit, but I try to explain that its in the school interests to follow the laws of Thailand.
