A former Florida bank manager who was fired for carrying a legal, concealed handgun is now firing back.

Ivette Ros, a 37-year-old single mother of three, has a concealed weapons permit. She says she was fired last year from her job as a manager at Wells Fargo Bank in Oldsmar, Fla. because she brought her gun to work.

Ros has now filed a lawsuit against the bank, alleging that being fired violated her constitutional right to bear arms. She says she carried her 9 mm handgun for protection in case of a robbery at the bank and says she never openly displayed the gun.

Wells Fargo spokeswoman Kathy Harrison told the Tampa Tribune that employees are “strictly prohibited” from carrying weapons on company premises.

But Ros’ attorney says the company’s policy is illegal.

Ros is seeking monetary damages and attorney fees.
