"you used a physical ailment as a safety reason for not completing your route. If you were to have used a form 1767 due to the "Unsafeness" of trying to deliver in the dark and possibly not having 8 hours between the next day's start time"
Actually, I read up on this a bit (I can't remember where I read it) but Delivering in the dark was not an acceptable reason. Possibly, the 8 hrs between routes (lack of rest/sleep) probably wouldn't work either since your logic of "physical ailments" (eyestrain, exhaustion, blurred vision) puts lack of sleep in the same category.
I am not sure how you ( rt2mailman, psd181) became contempt with management behavior regarding this situation-- [Well, your managers kinda got you on this one. Use it as experience and prepare for the next time.]- Rt2Mailman. [Actually management is correct here. If you fail to complete your entire route, then you must use annual or sick leave for that day.] -ptsd181
Ummm.....How about I challenge this today and correct them.
My 1767 states--"I am too exhausted to continue working today, I do not feel safe and will not put myself or the Post Office at a liability of getting myself injured or having an accident."
A 1767 is titled, Report a Hazard, Unsafe Working Condition or Practice. This is what I am doing. The only reason management is challenging this is to intimidate and retaliate against a carrier for not getting packages delivered which is going to "put them on the list". They do not care about you or your safety.
