I'm sorry that no one has responded earlier. If this reaches you too late, then oh well, I tried.
HR departments are created to protect the employer's interest. The only
reason why the HR department is providing you with a meeting, is to ensure that the employer has no liability for your termination, especially liability for termination based upon race, color, nationality, religion, ancestry, sex, sexual orientation, pregnancy, age or disability.
Other invalid reasons for the employer's concern is that an employee who is terminated in a manner contrary to the employer's disciplinary policy may create a viable wrongful termination action. This could give you a complaint for lost wages -- though generally not for reinstatement.
The point is that HR will attempt to obtain facts that protect the employer from liability. There is generally no interest in trying to assist you in being reinstated.
So, if your supervisor made an intimate advance, and you complain about it to HR, you will almost certainly be reinstated with back pay. Otherwise, the meeting may make you feel good, but it probably won't change the outcome of your employment termination.
Note: if HR offers you your old job back at a wage more than 80% of your old wage, but not 100%, then be careful, because if you reject the offer, you could make yourself ineligible for unemployment benefits.
Also if HR tries to satisfy itself that your conduct was gross insubordination (refusal to follow rules), then that, too could invalidate you from UI benefits. So, be careful, because people like to vent, thinking that they will get justice. Reality is the opposite. Better to say nothing at all.
Hope this helps.
