Well, I talked to him again today about a raise after I brought in another client. He basically told me that I make enough money and he isn't going to pay me more. For those who are wondering I make $500/week in a position that usually requires a college degree. He told me to go somewhere else if I wanted to make more money. I said you don't want me to go somewhere else and he said that he knows he doesn't. I am getting major mixed signals here. He ended the conversation by saying that he refused to talk about it any more. So what should I do? I guess I have no other option than to leave right?
You are not getting mixed signals. Obviously he wants you to stay. You knew that before the conversation. That's not what the conversation was about. The conversation was about whether or not he would give you a raise. The only signal you're getting from him is that he's not going to give you a raise. That signal is not mixed. The signal-to-noise ratio is extremely high here. You are not getting a raise if you stay.
Honestly, it sounds to me like the conversation went exceedingly well. When you say that he told you flat out that you'd have to leave to get a raise, that makes it sound like he's not trying to emotionally blackmail you into staying, or string you along with promises that he won't ultimately be willing to keep. This undermines some of the worst things someone reading your accounts might think about him, so I'm happy to hear it. Not doing anything to muddy the picture is really quite excellent of him. He's being honest and even fair with you.
In answer to your question: it is not quite correct that you have no other option than to leave. Your only other option --the default option-- is to accept your current pay and stay. Two crisp, clear, perfectly opposing options. Him caving aside, you could really hope for nothing better. I'm going to have to disagree a bit with Mr. Bear's assessment above, and suggest that your father is
not playing poker with you. Poker is a game of imperfect information. Your information is as near to perfect as it gets in family-mixed-with-career situations. That really is a blessing.
