The party who accused you must show proof or withdraw the complaint. It is not clear how prospective employers are getting this information; it is illegal for previous employers to make such statements about a former employer. They can only verify employment and say "yes/no" as to whether they would rehire. You may need to speak to a lawyer.
If the charges of elderly abuse were not proven in a court of law, you can take the company or individual to court for slander and defamation of character. If you win the suit, they will be given an order to stop the slander and you will receive payment.
You cannot simply be accused. The accuser must prove the allegation through criminal proceedings. If someone is accusing you and affecting your ability to get work, see an attorney as you likely have a defamation case.
If I have been accused of elderly abuse, the first thing I would obviously do is hire an attorney. This way, I am able to legally defend myself in a court of law and clear my good name.
The best thing to do is hire a lawyer and get a medical professional opinion from a physician. Some physicians, especially geriatricians or ER docs, can give legal testimony concerning elderly abuse.
Ty51: By hiring a attorney won't it make it obvious that you are guilty? If I was to accuse someone of abuse, and they hire a attorney, it would seem to me they are guilty, on the other hand, better say then sorry. : )
