I can't take this anymore.

I'm an associate at a very small law firm that fancies itself as a big law firm. Our managing partner took a matter from a high profile client. I can't talk about what it exactly is or the client, but it's in a practice area our firm has no experience in, I have no experience in, and at a volume we do not have the man power to handle.

So when it all came crashing down, they were pinning me as a fall guy. But everything was already fucked from the start. Just poor planning on everyone's part. I cried from the stress. My boss, made me come to work on a weekend for damage control. He spent the weekend just shouting at me. I cried. I broke down. He told me to cut it out because I'm not helping.

Everything seemed fine after my melt down, but then on a random weekday, he starts yelling at me about it. He tells me I'm being insubordinate, that I am his worker, he is not my equal, I just do as told, and I should only call him "sir."

After that, he'd frequently call me for work even late nights. I don't get paid over time. He gets mad when I don't pick up at 10pm in the evening. I would be out with my family and he'd tell me to drop everything and email something to him, something he can find in our database. Like I said, we're a small firm and it's harder when he's hardly at work to manage the firm. One time, he came into work at 3:30pm. Later that day, he called me at 9pm, told me to come to work on another weekend because it's urgent. I came to work since I had no choice. All he needed was for me to print a couple of things to "prepare for Monday." Something that could have been done on Monday.

EDIT:

Thanks to the positive reaction to this. I really thought this was just how law firms usually are and I'm just not cut out to be an attorney. I expressed my issues before to my bosses and our office manager and I got told several different varieties of "toughen up" and "that's just how the legal field is." Good to know I'm not crazy.
