USPS has........
Go thru this constantly. Sadly the USPS lives by the DMM....the Domestic Mail Manual. Logic need not apply when it comes to the USPS "bible".
Worked there for close to 20 years. The delivery issues are just the tip of the iceberg. Want to become a plant manger? Just sexually harass an employee.....promotions guaranteed. Of course part of your "punishment for costing the USPS a 300k payout in addition to any legal fees for the person you harassed will be a 6 month detail job in Hawaii. This will include a several hundred dollar a day "allowance"....needless to say the USPS will also be putting you in a resort style hotel. Wife not employed by the USPS? Not a problem, they will fly her out with you...and give her a couple hundred a day "allowance" as well.
Want to see how the USPS is treating employees injured on the job? Just enter USPS National Reassessment Program in your search bar and hit enter.....this is the very reason why my wife is collecting disability.
