Local 501 will be having our steward training this Saturday at our hall in Las Vegas from 9am-4pm. Food will be provided! Stewards are the front line of defense for enforcing union contracts and these trainings ensure our stewards are best equipped to advocate for the union—if you’re a steward in Las Vegas and you have not received an invite, let us know!
