I was recently terminated. A complaint of harassment and teasing was brought by a team member against other team members. I informed my store manager, and interviewed all involved, no evidence was found everyone said there was no problem. 1 month later another complaint. My store manager brought in regional staff to investigate. After the investigation, myself (ops mngr) store manager, admin manager, warehouse manager and 4 team members were terminated. I was specifically told that I did nothing wrong, but that I did not do enough.
I understand that Washington is an at will state, but I feel what was done is wrong. Do I have a case? Any recourse?
