I have been following the contract updates and it is my understanding that making MLK Day a holiday is one unresolved issue.
I believe that anyone who really and truly wants to have MLK Day off should be granted their wish.
That said, I also respect the reasons against pausing all operations at UPS for yet another day since this past Labor Day, traditionally one of the "major holidays" I saw Amazon drivers out delivering.
The solution I am informally proposing here, speaking for no one other than myself, but hoping to win other people over, is to have an additional discretionary day added to the contract which someone may choose to take on MLK day, or any other occasion, or receive a payout for the day at the end of the year.
As a general rule, I believe that the more options we give each other, the better off we will all be ultimately.
Some time ago, I started a thread asking if those in leadership at UPS or the IBT check out what is being posted here. Right now, I am really hoping they do though I am curious what even people who aren't in leadership think of my idea...and I figure I will find out soon enough...
