Just a note of caution: ECN really isn't interested in getting tied up in any manner of debate regarding unions in general. You can be sure this thread will b vry closely monitored.

Leaving a union is as simple as leaving the job. If you happen to work in one of those rare places where union membership is optional, your employers' human resourceses department can tell you what is necessary.

As you might guess, Unions are not in the business of losing members. Closely examine the impact your action will have on your medical benfits, pension benefits, etc., before you make the jump. You may also be required to obtain some other form of credentials - a 'union card' is only good for union members.
