According to a 2015 report from the Substance Abuse and Mental Health Services Administration, the food services and accommodations industry is among the top fields for alcohol and illicit drug use, alongside construction and mining. [...]According to the report, the industry currently has the highest rates of substance use disorder, at nearly 17 percent of its workers. That percentage is especially jarring when you consider that the restaurant industry is the second-largest private-sector employer. According to the Bureau of Labor Statistics, jobs in food service will soon outnumber those in manufacturing.But without union representation, these jobs are usually accompanied by poor pay, inconsistent schedules and no medical insurance. High turnover means that when substance abuse behaviors do interfere with job performance, workers can be easily, and immediately, replaced.Plus, the problem goes all the way to the top. The same report on substance abuse found that across all industries, one in 10 managers is abusing controlled substances. Middle management is arguably the most overworked in food service; in high-end bars and restaurants, managers often make less than their service staff, while working longer hours with no overtime pay.Because food service jobs are increasingly a foundational part of our economy, it is even more crucial to think about what happens to the people who work them.
