I am in retail management for a nation wide chain and I recently reported an incident of an employee grabbing his crotch area at me after being asked to do something he viewed as "female work". My manager informed me that this person just had a weird sense of humor and left it at that. After about 3 weeks of me asking him to take care of it he tells me he "spoke" to him but did not mention if any corrective action was taken. He still continued to work us on the same shifts and there were no efforts made to talk to the other employee present or follow up with me about my claim.The employee is now gone from the company but not for this reason. Should I report this to a higher manager (district manager) although I really don't want to get my manager into trouble?
