(CNN) -- The postal service may have to deal with some unhappy customers if its latest cost-cutting proposal gets the green light.
At issue -- a proposal to tack on an extra day or two of delivery time for regular first class mail.
"Why would someone want to use the post office if they know it's going to be slower than it already is right now?" asked one New Orleans resident.
The post office is on the brink of bankruptcy.
The change is meant to save around $2 billion, but it would cost about 28,000 postal workers their jobs.
That fact hasn't gone over well in Congress.
"This guy -- this so-called postmaster general should be fired because of a lack of any imagination or initiative is proposing the death knell for the great United State Postal Service," said U.S. Rep. Peter DeFazio of Oregon.
But Postmaster General Patrick Donahoe says it all comes down to dollars and cents.
"Things have changed in our business and like any responsible business you have to react to that," said Donahoe.
The post office does not get any taxpayer money but is under federal regulation.
If the plan is approved, it could take effect as early as April.
