I have been trying to mail a package at the Greenwich post office there is a sign on the front door that says due to staffing the lobby is only open from 130 - 330. I was there at 1100. Went back at 310 and the inside door was locked and that sign stated open 1-300. The person was literally walking out the door. Now they are not open on Saturday or Sunday. So due to the hours I will go to Albany to mail my package as they will be open. I know several people that have worked at this location and they all leave for the same reason it's not the pay it's the treatment they get. This is unreal
