Wendy's Worker with Down Syndrome Fired Because He Wasn't 'Normal' ... Sister Claims

The sister of the longtime Wendy's employee with Down Syndrome who was recently unceremoniously canned is lashing out at the franchise.

Dennis Peek worked at a Wendy's in Stanley, North Carolina for 20 years, was fired without notice a few days back, and now his sister claims managers at the fast food joint told her Dennis couldn't do his job like a "normal" person.

Dennis's sister, Cona Young Turner, wrote on Facebook, "I am heart broken to say they have fired him ... They told me was unable to perform the duties of a normal persons job."

She went on ... "His dream was to retire from there some day and he was looking forward to a huge retirement party, we may just give him that party and tell him he has retired because he does not understand being fired."

She now says Wendy's has offered Dennis his job back, but he's not biting. She also says she's looking into filing a wrongful termination lawsuit of a special needs worker.

Cona says Dennis was deeply hurt by the firing, but she's gonna throw him a big retirement bash.

We reached out to Wendy's ... The Carolina Restaurant Group tells TMZ, "We are committed to creating a welcoming and inclusive environment for our employees and customers. This was a very unfortunate mistake and lapse in protocol; we value Dennis, have been in touch with his family, and we are looking forward to either welcoming him back to work in the restaurant or to celebrating him in a big way should he choose to retire. Should Dennis retire and ever want to work again, we’ll also be happy to welcome him back."
