Be careful, someone has just experienced the problems of the ban starting again if you enter the country, even if you are on the list of countries that get visit visas on arrival you might want to do a little more research!
I believe, in the situation where you have entered the country on a visit visa and your ban has started again, you then have to approach you previous employer for an NOC, back to square one or stay out of the country for the new ban. So much for the contract you signed.
