A civil servant has been told to remove a GAA flag from her car after a complaint from a colleague in Strabane, Co. Tyrone.
The incident happened on Wednesday, when her car was parked at the town's benefits office.
The Social Security Agency said it had a legal duty to maintain a neutral workplace.
Aodhan Harkin, of Sigersons GAA Club in Strabane, told the BBC that a Tyrone flag is not offensive.
"I thought we had started to move on in this country," he said.
"We accept everybody else's cultures but we can't accept our own.
"I think there's something drastically wrong if somebody's offended by a Tyrone flag."
