Signaling both growing anxiety and growing solidarity brought on by the coronavirus pandemic, workers in a variety of occupations across the country are protesting what they see as inadequate safety measures and insufficient pay for the risks they are confronting.

On Monday, a contingent of workers who fulfill orders for the grocery delivery service Instacart stayed off the job, demanding greater pay and better access to paid leave and disinfectant.

A group of workers walked off the job at an Amazon warehouse in Staten Island on Monday, and a sickout called by Whole Foods Market workers is set for Tuesday. Last week, nurses in the Bronx protested a lack of protective equipment, and sanitation employees in Pittsburgh staged a protest over working conditions.

Labor experts and union organizers said anxieties related to the pandemic appeared to be widely shared among front-line workers across different companies, job categories and classifications. “Whether they’re an employee of a grocery store, or in this case an Instacart worker, they all have the same concerns,” said Bob O’Toole, the president of United Food and Commercial Workers Local 1546 in Chicago, which represents about 19,000 workers in the grocery, meatpacking and food-processing industries. The union has organized some Instacart workers and is trying to enlist more.
