I am on internship here, and it is no where stated that i can't work for any other employer.
Although it is written that i can't work in
1. Child care
2. Primary and secondary teaching.
3. Health related field occupation.
Do u have a contract? as for me I have a contract to my employer for 2 years! I guess if it's an OPEN WORK PERMIT ...It will state there that it is an OPEN WORK PERMIT and you can be able to work to any other job/ employer
