I am a Risk Manager so I work on the other side i.e. defend my company from lawsuits. Since I don't know the specifics of the case I am talking generally about EEOC claims. More times than not the EEOC doesn't take the case but give the employee the right to sue. So, the employee then gets a lawyer who will get between 30% and 50% of the settlement. The better lawyers generally want less, just an FYI. The dentist should have EPL insurance but the deductible will probably be $25K or higher, could be as low as $10K but that would be unlikely. So, with that in mind any settlement and legal fees to defend this claim come straight out of the company's bottom line. They will want to settle this, legal fees alone could be $10K. If I had to put a value on this case, I would say she would get a settlement of about $15K as long as she doesn't drag it out too long (the more legal fees the company has to pay, the less they will want to offer in settlement).
In these litigious times the facts of the matter barely come into play since the legal fees are so high. Companies defending these cases look for the best financial settlement which often has no reflection on the merits of the case. Sad but true.. however, in this case it sounds like your friend has a case. Hope that helped!
