My job

So my boss is being a jerk. I have worked here for almost four months with no days off, I come in no later than 9 every day and leave no earlier than 4. He shows up whenever he wants, and that's usually around 11 or noon, and leaves about the same time I do. He also leaves on vacation for weeks at a time and he has done this several times since I've worked here and I don't know about his vacations until a few days before he leaves. But that isn't what bothers me.
This is what bothers me:
Like I said, I haven't taken ONE day off since I've worked here, I work full 7-8 hour days and I don't ever call in sick, I take over his projects when he's gone and I have to deal with stuff I haven't been trained in, like politics.
So I wanted to take a long weekend this weekend to go to Seattle and just get out of town. Leave on friday and come back monday, no big deal, I made sure I would get everything done before I left and I would be back tuesday to pick right back up again, and I told my boss this about a month ago before I booked my ticket.
So yesterday he comes into my office and says "what is it you have going on this weekend? did you have something going on?" and I replied calmly "yeah, I am going to Seattle, I told you a month ago I would be gone Friday and Monday"
"friday AND monday?! are you sure you have enough vacation time saved up for that?" he asked me with a raised brow and a heavy condescending tone.
"Well, yeah, I think i can start taking vacation after three months and I've been here for four without taking any days off"
long pause, looking at me with his judging eyes "hmmmm".
I rolled my eyes when he couldn't see me and figured that he was just being stupid and it would be fine. so our boss in phoenix calls me and I come to find out that my boss here had called him and told him that I shouldn't be given the time because we had a lot of stuff going on and I should be here to take care of it.
WHAT AN ASSHOLE!!!!!
So looks like I need to call our Phoenix boss today and explain to him that I do deserve the time off because I work really hard and deserve two days off out of the almost 120 I've worked here. Oh yeah, that includes weekends because I definitely have to work weekends a lot of the time.
this is such CRAP.
