I was recently recruited by a large Aged Care facility. I attended the orientation day and signed a contract with them for a P/PT position. 6 days later, I received a phone call stating that the offer of employment was being withdrawn. When I asked why, they responded with " you are no longer physically capable of carrying out the duties required" In other words, you are too old. I am 54 years old and have been in this industry, in this role for 20 years. Can they legally do this to me under employment law?
