I have a WP based on my teaching job, now I did my fitness certification here in Bkk and I am getting (not too many , but 2 or 3 ) offers of personal training which I would love to take as practical exp as I am a fresh meat in fitness industry. Do I really need a permission from my primary employer to get my "extra work" listed in my WP ( from DOL) or it's a mai pen lai affair ?
