I'm a disappointment to the firm

As the title says, I am a disappointment to my employer and to my firm. My boss brought me in for a chat the other day and had some strong words regarding my work ethic. He suggested that my work ethic was not up to the firm's standards, and I should be arriving to work by at least 7 a.m. and stay until I am the last one at the office. He also claimed that I never have worked on the weekends, which I corrected him and said I have. Yet, he made it a point to say that he checks the security cameras often and never has seen me come in on the weekends (again, a lie). Mind you, I work at a personal injury law firm and I am always on top of my work load. He went on to tell me that to be a top lawyer, I need to be working 24/7 and that my work product has been "shit." Funny however, I am aware he's bragged about my work product around the firm and to outside lawyers... Anyway, after berating me with hateful comments about how I should reconsider this job and "really think about if this firm is the right fit for me," he suggested I should go find a government job instead. He also named multiple local lawyers to make a point that I "can go be a piece of shit lawyer" like one of them instead of working at his firm. He finally concludes this conversation by telling me that I have been a disappointment to him and to the firm for the two years that I have been working for him. I also apparently am too incompetent to work up my own cases.

With that being said, I think it's time for me to find employment elsewhere. Perhaps I will hang my own shingle. I honestly don't know, but I do know that he's right, this firm isn't a right fit for me. Why would I want to work for someone who is going to role play as my father and tell me I am disappointment?

That's all. Thanks.

Sincerely,

The Most Disappointing Plaintiff's Lawyer.
