Contract abuse? - MTinIA

Hi,

I have a big dilemma and I need help. I have been working for the same company for 6 years now. At first I worked for a bunch of doctors and a hospital and then quit the other docs and the hospital because one of my doctors said that he did not like to share and that he wanted me to work only for him. I did not know that was illegal to do until recently being that MTs are contractors. So I have been working for this one doctor and all the nurses and interns in the office for about 5 years now and the situation has been really really bad for about 3 years. I get constant phone calls asking if I can please hurry up and do this patient and it amounts to about 4-7 phone calls a day because so and so has a procedure Monday and I get calls from the front desk girl asking if i can hurry up because this patient was just seen today and she really needs to get that auth. I get phone calls and emails from their sleep lab also asking me where Mr. so and so is from 2009 and if I have it can I please send it. Ic have been trying to quit now for a year and each time the office manager tells me "well no one understands him" (he is foreign), or "ok we will get someone else" and then they never do it or like this time, I gave a 2 week notice and the office manager said "oh he doesn't want to lose you, but he is willing to find someone else for the nurses". My quit date is supposed to be June 30th but I once again felt guilty and said that I would continue to do his work only. On Friday the office manager accused me of making the other girl quit who was helping out withthe nurses and that was it. I was mad and it's Saturday and I am still angry. I am burnt out from 6 years of abuse and I start school next month and I need out. As I was researching what is legal in terms of quitting as a contractor, I came across info that my cointract is also invalid because my brilliant office manager told me in February when I was supposed to renew, that I did not need to renew yearly as the contract does not have an expiration date. Come to find out, this can bring a whole mess of stuff from the IRS down because that would imply I am an employee rather than a contractor-however, all of the above would indicate employee status and they have been misclassifying me. This physician is getting away from the medical group and flying solo to private practice with the same office staff on July 15th. I do not want to sign another contract and the way I have been (feeling) abused makes my stomach sick. It's very hard to make myself get up to owrk, not to mention I have 3 children all under the age of 14, they are on summer, i start school next month and my husband comes home from Afghanistan in August and it's hard to prepare for all of this being chained to my desk all day. I need advice here please. How do I get out of this job?
