I worked many years as a postal employee.
I was also a union steward and chief steward.
The NALC and APWU are just like any other
organizations. There are "politics" and "favoritism"
and "discrimanatory practices" abound.
BUT WHY are you giving Union a hard time?
Your management also looks like they've
discriminated against you.
CALL THE NATIONAL IN WASHINGTON DC.
FILE A COMPLAINT WITH THE NATIONAL.
FILE AN EEOC COMPLAINT AGAINST POSTAL
MANAGEMENT AND YOUR UNION OFFICERS.
YOU CAN ALSO FILE LABOR CHARGES.
POSSIBLE LAWSUIT DOWN THE ROAD (against
Post Office AND Union). Remember you have
to give PO a six month "warning" letter before
you sue them.
