The labor law in Thailand is NOT gray
Postbox letter from Jonathan
There is no gray area here. Always go with a Thai. Always speak to a supervisor if anyone tries to fob you off with the 'this doesn't apply to you' crap. Nearly all schools will settle at the initial arbitration meeting.
With regards to severance pay
Postbox letter from Walter
My friend was awarded 90,000 baht and the school had to pay it.
Severance pay issue
Postbox letter from Mr John
I also investigated the possibility of getting severance pay as a previous employer did not renew my contract after three years of service.
Be careful with that resignation letter
Postbox letter from
I realize that there is an appropriate time for a resignation letter. However, in a situation where you have not been offered a new yearly contract and you did not violate your contract in terms of paper work or duties and nobody is telling you anything then the Thai Administration's seemingly harmless sign this resignation letter document is not in your best interest because they will not have to pay you anything regarding severance pay.
