Input: Some background, I work in a small store that is part of a major industry. It's half retail and half physical labor, and recently we got a new Manager here at the store. Let's call him M, and besides M and myself we have one other full time employee, I am part time *just* below full time. Basically I work enough hours to be there enough to live, but just little enough that the company doesn't have to give me benefits.

Now, before M showed up we had a previous Manager with whom myself and my co-worker had no issues with at all. Previous Manager kept enough jobs moving through where we would hit bonuses and all around do fine monetarily. But i was asked to work Saturdays solo, since they both had newborns in the home.

This was fine with me, I jumped at the chance to get that 9 hour shift. The flip side of this is that I was off on Mondays, and over time Sunday and Monday became my days to take a breather. Before long, Mondays specifically became my time to go to CMA meetings in support of one of my close friends, who is recovering. This specific fact never came up with co-worker/ex-boss because, well, they never had any issue with me being off Mondays so I went about my business.

Fast forward to a few months later, old boss leaves the company, new guy moves in. Things begin to change in terms of, well there's more for us to do. I take on more duties (for no extra pay or hours, though they say "you should've been doing this anyways), and the new boss who is money driven, damn near doubles the amount of physical work we do in the store. We work with paint, so we shift probably 8,000 gallons in a week, sometimes less, sometimes more.

One thing he consistently begins bringing up to me is having me work Mondays. I've refused flat out multiple times, for two reasons;

 1: I'm going to support my friend, no matter what. This guy was there for me in a big way before he fell on hard times, so I will return the favor. 

 2: I would be working 6 days a week, with no extra hours at all.

See, he can't get approval for me to technically work more. So he wants to spread my hours out across the week so I'm there more days, same pay, less days off. It's gotten to the point where when I come back on Tuesdays, he'll say "me and [co-worker] did x amount of work yesterday, because you didn't want to come in to work." Like he's guilt tripping me for having days off. 

I'm still the only one who works Saturdays, alone. Beyond this, there is a boss above him, who has even said (to the new manager, as advice about me/this, and I heard about it) that my "days off aren't a garuntee." Which is just...disgusting, to me.

Am I the asshole for refusing to do this? Also, I have talked with my co-worker, (with whom I helped keep the store open during the two week no manager period while the new guy was getting hired), and they have no issue with me being off Mondays.
