DENVER (AP) — A pre-pandemic shortage of licensed commercial drivers in the waste management industry has become worse. Now, cities and companies are dealing with a shortage of workers to hoist trash into the trucks. The Denver Post reports workers in the solid-waste industry were considered essential workers as COVID-19 started to spread. But now there aren’t enough of them, and many are likely looking for different lines of work or better pay. The shortages are occurring across the country and are leading to delays in pickups, particularly in recycling. The solid waste industry is among those using signing bonuses to lure back workers.
