The Denver City Council has approved a $30 million contract with ASM Global to manage stagehand staffing at Red Rocks and other city venues after discussing concerns about the company’s compliance with city wage laws. That unanimous vote was taken Monday after some council members warned that they planned to keep an eye on ASM and other city contractors to ensure those companies adhere to local wage rules. Councilwoman Sarah Parady, a labor attorney, postponed a final vote on the contract at the council’s April 22 meeting and then called it out for comments before the final vote.
