no she no need to be at the airport, but must be available by call in case the officer asks.
I feel most probably when you already have multiple entry valid visa with the remaining days to stay and you have traveled once. You will be happily allowed.
Technically if your work permit is canceled the visa is cancelled too. You should not over stay. Please leave the country and in case you need to wind up fully if you are not sure when you are getting your work permit again. You may go to a nearby country and come back with your visa on arrival, I will allow you to have some days here for selling the stuff or other things. .
