Construction workers at a giant granite construction site in Arizona are expected to strike on Wednesday.
The Local 637 of the American Federation of State, County and Municipal Employees Local 713 represents construction workers at the Grand Canyon-Parashant granite quarry in Arizona.
The union says its members have been working for years to unionize, but it has never been successful.
It’s calling for an immediate stoppage of work at the quarry.
