I have a problem with this. On the one hand, if a union is negotiating and I gain the benefits of its work, I should in justice and good conscience pay my fair share for the benefit I am getting. On the other, once I leave a company I should not have to pay union dues if I'm not working there. However, if I am keeping my union affiliation despite having left the job then, yes, I should keep paying. The wording of the law should be changed to be more explicit.
