Food industry workers are turning towards non-traditional unions and organizing tactics in order to attain greater wages and working conditions. In the past, food industry workers have struggled to organize and to make gains due to public perception of their positions being temporary, and primarily held by young people. According to the Bureau of Labor Statistics, around 1% of food workers are union members compared to around 10% of the general workforce. Now, the IWW and the Fight for 15 have emerged as key players in this renewed movement that uses aggressive tactics, such as salting, to secure benefits for these employees.
