A Liberal MLA says he would probably think twice about allowing a private company to use his constituency office to conduct job interviews again, given the criticism he has faced from the Progressive Conservatives.

Bill Fraser, of Miramichi, recently let the city's new Giant Tiger store, which his brother manages, use his office to interview people applying for positions.

The Tories contend people who get jobs at the store may feel they owe a political debt to the MLA.

Fraser said he'd offer his office to any company hiring in Miramichi, and got permission from staff at the Legislature to do so.

But now that Progressive Conservative politicians are using it to attack him, he says he probably wouldn't do it again.

“The unfortunate thing is in the future I think I would have to think twice before I would do it, based on what has happened," Fraser told CBC News.

"Nobody likes to be under attack. It's one thing to attack me as a local MLA. It's another thing to attack a company who is investing hundreds of thousands of dollars into a region."

Giant Tiger officials have said they were unaware of the situation and are looking into the matter.
