There's new criticism over big changes planned by the U.S. Postal Service. Some say ending Saturday delivery of first-class mail goes too far.

This is getting a lot of criticism, particularly from rural lawmakers and letter carriers union, which is worried about layoffs. The postmaster general says he can end Saturday service without cutting jobs -- he can just cut overtime, and allow more retirements -- but he's still going to face a fight.

The Postal Service's plan to cut Saturday delivery came as no surprise to many Americans. One man told CBS News, "I think it's a real good thing. I think they should've done it years ago."

But not everyone is giving it their stamp of approval. One West Virginian said, "It would affect me. My business mail that comes on Saturdays. I would miss that."
