Can I sue my previous employer for requiring me to perform illegal acts?

I reluctantly resigned my position as a pre-need funeral counselor in the state of NC on March 3, 2013. I left the job because I believed the funeral home was violating NC insurance laws by requiring me to provide insurance to clients while I was not licensed. My employer believed I could continue doing my job as long as a licensed funeral director and licensed insurance agent were in the same room with me while I sold insurance to funeral home clients. After leaving the job, I was initially denied unemployment benefits. After appealing the case, I was awarded unemployment benefits on January 9, 2014. During the telephone hearing, it was concluded from the competent evidence in the record and the facts found that I had good cause for leaving the job and that such cause was attributable to the employer because what the employer asked (claimant) to continue doing might well have exposed (claimant) to prosecution for violating North Carolina insurance laws. This information is on file and has been recorded with the NC Dept of Commerce Div of Employment Security. I am currently still unemployed now after a year. I have been applying for jobs but have a feeling the employer may be "blacklisting" me, but I do not know for sure. I have exhausted all my retirement funds in order to live. Can I sue this employer for damages?
