Legal Question in Employment Law in California

In general, employees are 'at will' and can be disciplined or fired any time for any reason, with or without �cause�, explanation or notice. The company didn't need, but had, and explained, 'cause' for your firing, the harassment complaint against you. The company is obligated by law to investigate and take action on such complaints. They did.

You were fired for harassment when someone complained about the conduct you 'admitted' to in this post. Whether you understood it was harassing or not, the victim reasonably believed it was. That is what matters under the law.

Your understanding of the situation is entirely backward: you haven't described ANY basis for a complaint against your 'victim' or the company, whereas the 'victim' could potentially sue both the company and you. That is one of the real reasons you were fired - to show their legally reasonable response to a complaint of harassment.

On the facts stated, you should walk quietly and quickly away from this situation, drop any claims, seek new employment [which may be difficult with a harassment based 'for cause' firing on your record], and read up on what is considered 'unwanted attention' and 'harassment' in the workplace so as to avoid future problems.
