Something to consider.
However, I am questioning the moral legitimacy of UPS's authority to force me to work a Sunday when past practice for over 30 years has been to never force package to work Sunday. If indeed the necessity of forcing work on Sunday can not morally justified, my moral obligation to notify them would be negated.
I am not worried in the least about a warning letter. And any work not completed Sunday would just roll to Monday when it sould have been done anyway.
Still sorting it all out.
UPS has
always had the contractual right to operate on a Sunday, subject to dispatch rules that require the work to first be offered in seniority order and then forced in reverse seniority order.
By choosing to accept employment at UPS, you agreed that your wages and benefits and working conditions would be defined by that contract.
Per that contract, you are
required to inform the company in a timely manner if you are not able or willing to report to work on a day where you are scheduled on the dispatch.
From a
moral standpoint..... I would say that if you are going to enjoy the
benefits of a labor agreement you have an obligation to live up to the
responsibilities of that agreement as well.
