I might as well throw in on this forum since I can lay some ideas on anyone who is like minded.
I used to EEO any postal manager who looked crosseyed at me. I did so , in many instances just to put them on the defensive to leave me alone and move on. I would wait until they had to wear themselves out with "postal paperwork/homework" and then I would withdraw the EEO after the post office had wisely given some higher salaried joe-college sociologist, the job security of researching "allegations." When the EEO came back for either inervention/one-on-one, or farther along, I simply dropped the case. I don't wish to discourage anyone from filing but I learned that the inconvenience and personal committment that I was able to delegate to a postal manager who required an attitude adjustment would suffice, and that was always enough for me.
I was able to quickly realize that all EEO's, legitimate or "almost," still have merit, in that management fools will build a case for you in the form of retaliation or anything that appeared to be.
I would simply relate to the person I had EEO-ed, that I "appreciated their retaliation because it gave me a much stronger and irrefutable case."
It didn't take managers long to look the otherway when I came around and to "get busy with other important issues."
That is all the hell I ever wanted anyway.
I encourage everyone who needs to help a postal manager with their attitude, File an EEO! You can always drop the damn thing and they can always "kiss your ass."
You see, management never knows how far you are personally willing to go once you call their bluff. Just be willing to go all the way with the fools who think YOU are bluffing.
