FORT LAUDERDALE, Fla. -- A South Florida woman says that she was fired from her job with the Florida Marlins after bringing her daughter to work on national Bring Your Child To Work Day.

"I took a picture with my mom at the Pro Player Stadium. It was a great day," said 11-year-old Brooke Hernandez.

The Story In Pictures: Marlins Employee Fired

For Brooke, a visit to Dolphins Stadium was an experience she won't soon forget.

But it wasn't the baseball diamond where the Marlins play that left the lasting impression. Rather, it was the consequences her mother faced for allowing her daughter to participate.

"She got fired," Brooke said.

After 12 years with the Marlins as an accountant, Nancy Hernandez was given her walking papers Tuesday morning after bringing Brooke to work last Thursday.

"It made me feel sad," Hernandez said. "It made me feel mad. You know, I have been working there for 12 and a half years. I love everyone that I work with. I give 110 percent."

But Hernandez's exemplary performance was not enough to keep her from being called out.

Employees at Dolphins Stadium acknowledge the national program, allowing workers and their children to participate. But an e-mail from the Marlins human resources director stated, "We will not be participating in the program this year."

"Nowhere in this e-mail has anybody told me that we were forbidden or I would be fired for that," Hernandez said.

But she was fired and paperwork from her exit interview cited, "Violation of a clearly stated company decision, insubordination, not saying the truth."

Sporting her 2000 World Series ring, Hernandez said in her 10 years she has had many wonderful experiences and memories with the Marlins but that's now all in the past.

"This was a lifestyle for my family and my kids," Hernandez said. "They love the Marlins and love going to the games but this will all end now."

Hernandez said she is still in shock and not sure whether she will take legal action.

A representative from the Marlins organization told NBC 6's Sharon Lawson they will not be commenting on the issue because it is an internal matter.
