Rain, snow and sleet may not stop the post office, but a massive budget deficit will.

The head of the U.S. Postal Service is asking Congress to limit mail delivery to five days a week, instead of six. Postmaster General John Potter says cutting deliveries will help cut costs.

According to Potter, the way people communicate has completely changed over the last decade. He says less revenue is being generated as more people use the Internet to pay bills, get bank statements and send correspondence.

The move has residents and postal workers worried about the possible repercussions. Postal workers say cutting one day of delivery could hurt customers. Residents fear they will have to wait another day longer for important items.

Potter didn't specify which day would be cut. The proposal still needs approval from Congress.
