I kinda screwed myself, but its okay to be mad at my boss for it, right?

So here's the deal:
my assistant manager and myself work ridiculous hours - like not just a lot of them, but at odd hours of the day. For example, my shift is 5pm-3am - and once a day I do a turn around where I then open at 9am. All of this I have accepted begrudgingly because I need my job...grrr...
We ofter work extra days as well, so its pretty much a standard practice around here to try and get those days back when it comes to holiday break periods.

This week, I took my normal Sunday/Monday (following assts' Friday/Saturday). What I didn't keep in mind this week, was that my businesses close this coming Friday, which means that we will both be off Saturday - her normal day off. Therefore, she is basically owed another day in my opinion.
Now what my boss would say is, you shouldn't have taken off both Sunday and Monday because you will have Saturday. Well, I didn't think that far ahead! Too damn bad. Rather than address this with boss-man, I decided to take care of it myself and just appoint today my asst's other day off to make things even. I already had coverage scheduled by coincidence because I was initally scheduled for an 8am mtg before I worked a closing shift.

So I tell asst to take the day off and not to worry about it. If bossman calls, I will make some shit up. Which I end up doing. I explain that I owe her a day off from extra days worked in October - which is actually true, but not the real reason that I did it. Well, now bossman calls late tonight and finds out that I have additional coverage and bugs out. He calls my cellphone frantically, and leaves me a nasty sarcastic message about the situation - insisting I call him back.

I call 5 times I think, and he never answers. I leave messages, he doesn't call back. I'm like a goddamn monkey starving behind a darkened glass window with a bunch of people with bananas on the other side going, "nah...." I HATE feeling like a chimp, and I suspect this is precisely the effect my boss is going for.

So I am a little mad at him right now, mostly because I work harder than all of his other managers combined, and part of me feels I am owed some small gesture of understanding in this case. But I guess I kinda left out the other part of the truth, so I guess I'm an ass too.

The worst part of all this: because I care so much about my performance, my job and my reputation - any shread of doubt I have in myself and my job security surfaces right about now, and I will not get any sleep tonight. not a wink. In fact, I only got 2hrs last night, and I have to get up in 7hrs and I am still here typing and hoping that putting all this in writing will ease my not-really-guilty conscience and make this all go away.

Here's to hoping.
