You are not allowed to make untrue statements of fact that are damaging to a person’s (including a company) reputation to a third-party. This is called Defamation and the aggrieved party can sue you.
While “untrue statement of fact” might seem to be an oxymoron, what it means is that the statements that you make are about things that can be objectively true or false - that Donald Trump is the worst President ever is a statement of opinion, that he was impeached twice is a statement of fact. You cannot defame someone by stating an opinion but you can by stating something that has a factual basis and being wrong about it.
You being “sexually harassed” is a statement of fact - you either were or you weren’t. While I do not doubt that you were subjected to unpleasant behaviour, whether that rises to the legally accepted definition of sexual harassment in your jurisdiction has never been tested. It hasn’t been ruled on by a court. So, a statement that you were sexually harassed is simply not true - if you say that, you are potentially defaming someone.
What is true is that you were subjected to X, Y & Z specific behaviours (that you can definitely prove happened), that you reported them to the company, and that you were dissatisfied with their response.
As an analogy, you can’t call someone a murderer just because they kill somebody. You have to wait until they are convicted of the crime.
