Well if they are harassing or taking corrective action 3 hours or more over, shouldn't they be taking corrective action for 3 or more hours under. Isn't this disparate treatment, if they are not?
I thought the evaluation compared to hours worked was based on numerous things throughout the year, mail volume, mail quality, weather, road conditions, etc..
If you have been doing your job for 25 years, you must have been doing your job satisfactorily, so they could adjust route after 25 years of good service? Doesn't sound like that part of the rule helps.
Now 55 years or older, what is the exception
They shouldn't be able to harass you regardless, if nrlca can't help you with this, what good are they.
File a grievance for harassment and good luck.
I don't know.
