(Portland, OR) -- Mail carriers protested Sunday afternoon outside of the East Portland Post Office against a proposed contract that's supported by union leaders. The contract has a 55 percent cost of living adjustment, and one-point-three percent wage increases for three years. Union members say it doesn't keep up with inflation. They say the contract also doesn't address mandatory overtime, understaffing, route adjustments and severe weather conditions. Their previous contract expired more than a year ago.
