Some of our new Letter Carriers probably wonder what the National Association of Letter Carriers (NALC) is all about or even wonder what the Union is even needed for. I will try to explain it the best I can here in this article. For one, if we didn't have the union we would have no job security what so ever, management could fire you just because they felt like it, even if you did nothing wrong. Some of you reading this probably think they can fire you for anything now. The fact is the only time they can fire you without the Union getting involved, is during your 90 day probation period, that's it, after that you are protected by the NALC.
