Work permit just expired

[wildside]

Due to unavoidable reasons, the school I teach for did not get to renew my work permit on time. It expired last May 20. A new wp application is now in the works.

I do have a few questions on this.

1. I am back to square one, right & do have to apply for a completely new work permit? Or could there be any chance still of renewal?

2. Do I have to turn in my expired wp to the labour office or can I just keep it for souvenir without any consequence?

3. Another school wants to hire me part-time. Can I just add this work on the same permit once it is issued for the first school? What are the differences in the procedure, if any?

I'll be looking forward to receiving any comments and advise any of you can offer me. They'll sure help me in ascertaining my status and options. Thanks a ton!!!
