It is illegal for a school to keep your work permits now. No matter what they tell you. You must have access to them.
I am trying to open a bank account but I need my work permit. I want to get a loan from my present bank and need my work permit. If you need to make payments at a hospital they want to see your work permit. Now if you cross the border depending on the officer (at at various check points) you need to have both your passport and work permit to provide you are not using fake stamps.
I was just told that I would be fired if I asked for my work permit again to open a bank account. The school said have them call us. The banks don't care who the school is. They don't know the people from Adam and they could be anyone. They want the work permit.
So my school refuses to let me cross the border to see my family, open a bank account or do anything that requires financial proof of income. They literally stole my work permit from me. In the government web pages it clearly says you must carry the work permit with you and especially, keep it at your place of work during working hours. Not 24/7 but some schools will not understand the wording and threaten you. I was told if I ask for it again they would cancel it and I would be terminated immediately.
Beware....you only have to give them a copy of the work permit when they ask. Do not give the original. Also, when you cancel the work permit you must get three pieces of paper from the labor office to leave the country to get another visa. A receipt (free), stamped copy of the returned permit and a work history copy to present at the border. If you don't have these and you try to cross you will be held, sent back to province to get them and on overstay.
