A new visa rule that has been proposed by the current administration has labor advocates concerned that wages may decrease for domestic farmworkers. H-2A workers’ wages are based on the Adverse Effect Wage Rate, which is calculated annually, and the federal minimum wage. Employers are required to pay workers the wage that is higher. The administration has proposed a change that will alter how the AEWR is calculated which would lower the hourly wage that employers must pay workers in order to help growers.
