As the House Committee on Education and Labor Subcommittees on Workforce Protections and Civil Rights and Human Services examine vaccine mandates in the workplace, I am writing to share our concerns regarding the obligations of the executive order requiring vaccinations or COVID-19 testing through an Emergency Temporary Standard (ETS) at the Occupational Safety and Health Administration (OSHA) or the Mine Safety and Health Administration (MSHA). Since the start of the COVID-19 pandemic, aggregates operators have taken aggressive actions to protect workers, as they continue to produce America’s essential building materials. We support the overall goal of vaccinating Americans against COVID-19 and have launched a national vaccination campaign in concert with our member companies. Our member companies have also taken action to encourage vaccinations, including providing time off to get the shot; additional vacation days; and offering cash rewards and other incentives, valued in the thousands of dollars, to employees and their family members who get vaccinated. NSSGA has also partnered with MSHA to amplify their vaccine campaign message and is working with the agency as they pilot a program to bring vaccine vans to mine sites.
