How long can the eeoc take with an investigation pertaining to discrimination and harassment?

It's anyone's guess. Every case is different. A lot depends on the investigator also. The EEOC is overburdened with the number of charges filed so it would be a good idea to consult with an employment attorney to see if they would like to take on the case and pursue recovery through litigation. You may request the notice of right to sue within 180 days of filing. However, an attorney may be able to request it early.   Ohio employment lawyer www.mcoffmanlegal.com
