So, you've been issued a "Right to Sue" letter by the EEOC. Does this mean you have a great case and all you need is an attorney to file your lawsuit?
No. You may have a good case (or even no case), but a Right to Sue letter is not decisive of anything. It simply means that the EEOC isn't going to represent you, but you still have a right to pursue your claim. This seems counter intuitive, but let me repeat: the EEOC hasn't concluded anything by issuing this letter - except that they won't be pursuing your claim.
The EEOC gets about 80,000 charges of discrimination each year but only files about 300 lawsuits a year. Private employment law attorneys handle the rest of the cases. Note that the EEOC must first issue a Right to Sue letter before an attorney can file a lawsuit. That's why your first step should be to contact the local EEOC office. Here's the information for the Oklahoma City office:
215 Dean A McGee Avenue
Oklahoma City, OK 73102
The EEOC office also provides a lot of informative handouts to help walk you through the process.
