Sorry bit of confusion on my part....
My Bangkok employer has ended my current work permit on the 28th Feb, my new employer in Phuket starts March 1st, (I need to be at phuket immigration 9am March 1st)
Basically I'm wanting to know if I need to leave the country and enter again on a different visa, or if I get the 7 days to get to phuket and start the new work permit.
