I was at the Keene, NH, Post Office about 6 months ago, 3 postal workers were not at their stations as a line developed out the door. An elderly man using a cane, started to get vocal, about being in pain, waiting for lazy, arrogant Postal Workers to feel like doing their jobs. A citizen "going postal", or just mildly complaining about this citizen abuse could be subject to arrest for exercising Free Speech.
Maybe two decades, or so, ago, the Postmaster of the Monson, Massachusetts, Post Office was on vacation. Invitations to a high school graduation party were put in the mail drop box in front of the Monson Post Office. A band was hired, tent for large outdoor gathering, chairs, tables were rented, large amounts of food was bought, temporary workers hired for the gathering. Almost no one showed up because the invitations sat in a blue USPS mail box in front of the Post Office, not delivered. Those who were in charge didn't empty the drop boxes for the entire time the Monson Postmaster was on vacation. Postal workers did little to nothing. Instead of firing the lazy postal workers, the Postmaster was suspended, and may have lost her job. The parents who threw the graduation party where almost no knew of it beforehand, considered suing the un-sue-able, the USPS.
I knew a Vietnam War Veteran who came back from war, drug addicted and alcoholic. He became an East Longmeadow, Massachusetts Postal Worker drinking on the job, and then very heavily driving his own vehicle home to Monson, Mass, where he sold his house, not to kill his neighbor using a shotgun for the neighbor's dog going number 2 in his yard. He told me that those who drive the standard, small USPS mail delivery trucks were required to chock the wheels and turn off the vehicles at every stop. USPS workers realized that if they started the trucks, then turned them off, started them again, and repeated this process in one spot, the battery could be killed in the truck and they could get overtime waiting for the truck to be towed. Soon there were dead postal delivery trucks and gaggles of overtime paid out. That is also theft of your tax dollars by lazy, and out of control federal employees.
Civilian Oversight of police, state, and federal employees would help solve this problem. So would a people's grand jury system.
I highlight more of this type of behavior here on this blog. I post documentaries and video here.
