How many certified warning letters have you received in the mail? I had never received one until the past six months when I have gotten 2 of them. One was for a C.O.D. discrepancy that I had already rectified and the other one was for a Class 2 Exception violation. (We are supposed to scan all clerk packages with a scan gun when we come in in the PM before giving them to the clerk) I pulled the packages off the car before leaving the building in the AM and didn't scan them. (It was a futured bulk stop) I have never gotten one for a service related failure. (missed, etc.) Anyone know how many you can get before they can you? It's kind of messed up that they send it certified to your home. It's psycological warfare if you ask me. By sending it to your home, UPS is involving your family in their discipline of you. They do it to worry your family that you will lose your job so the pressures increase on you from home. If you ask me, talking to you in a meeting with a union steward is enough.
