OAKLAND, Calif. (KGO) — For Kenyetta Gentry, the Oakland A’s are part of her family’s DNA.

“My grandfather worked as a security guard here in the 80s – I know that. If not, even longer. And my aunt, Aunt Pat, also worked security here,” Gentry said.

A tradition in which Gentry took part.

For 24 years, she has worked for Aramark, the company that runs the stores and concession stands for home games at the Coliseum.

After all those years of service, Gentry said she was shocked to learn Monday that Aramark would not offer severance to its employees after the A’s final game on Thursday.

Additionally, Gentry says she and her colleagues will also lose their health insurance.

“I’m very angry, still angry that they didn’t give us anything. Especially because we worked here for so long. Sweat, you know, tears,” Gentry said.

On Wednesday afternoon, Gentry and several of her colleagues held a news conference with her union outside the Coliseum gates.

They say Aramark led them to believe for months that they would ultimately be offered some form of severance pay.

Now, many of these workers are unsure what they will do next.

Robert Preston has worked here for nearly 40 years and relies on the health insurance his job provides to cover some of his expensive medications.

“I’m old enough for Medicare, but Medicare doesn’t cover all medications. You know, I’m diabetic, I have high blood pressure and I need oxygen,” Preston said.

We reached out to Aramark for a response.

They sent us a statement that read, among other things:

“We are negotiating in good faith with the union about the impact of A’s departure and stand ready to offer those affected vacancies in other areas of our organization.”

This is of little comfort to many of these workers, who fear that there is no guarantee that this will happen.

Despite the hardships these workers say they face, they all tell ABC7 News they will miss the fans.

And to all of these people, Gentry has only one thing to say.

“The smiles on your faces – we grew up as a family. And thank you for thanking us for our service, for doing a great job,” Gentry said.

The union said it had asked the A’s to assist it in its negotiations with Aramark, but those requests were unsuccessful.
