Last month, Walmart Inc. was hit with class allegations in California that it ran afoul of federal and state labor law by failing to pay workers for time spent on mandatory pre-shift COVID-19 screenings.

And this week, Arizona Walmart workers hit the retail giant with a $5 million proposed class action Monday, alleging Walmart required employees to arrive at their shifts early to undergo COVID-19 screenings but flouted the law by failing to fully compensate them for their time.

Workers filed the putative class action in Arizona federal court, claiming the Arkansas-based retail behemoth required them to arrive at their shifts 10 to 15 minutes early to undergo mandatory COVID-19 screening but didn’t compensate them for all that time.

Plaintiff attorneys say the screenings involved standing in line with co-workers to get temperature readings and answering questions about health conditions, recent travel and potential exposures to anyone with the virus. After passing the screening, workers were given masks and gloves. Only then were they allowed to clock in for the day, they allege.

Walmart, however, maintains that it has compensated its hourly retail associates for pre-shift time spent undergoing COVID-19 screenings. A Walmart spokesperson told Law360 on Monday that its workers have received compensation for the “extra time” they spent being screened for symptoms of the virus.

“All hourly associates have extra COVID screening time systematically added to their daily shifts and paychecks. This is in addition to our manual process for adding extra time if there ever is a reason this additional time is not sufficient. We will respond as appropriate with the court once we have been served with the complaint,” the Walmart spokesperson said.

Walmart workers aren’t the only ones seeking compensation for virus screenings.

Earlier this month, Apple was found to owe a class of California retail store workers for time they spent working off the clock undergoing bag checks. The amount of damages will be determined in a jury trial.

This March, a New Jersey federal judge ruled that Amazon warehouse workers seeking compensation for time spent in obligatory security screenings could amend their complaint to include a claim for compensation of pre-shift time spent undergoing COVID-19 screenings. The amended complaint alleges the tech giant should pay workers for the time they spend getting their temperatures taken and answering a COVID-19 questionnaire prior to their shifts.

That same month, workers sued a California tennis company seeking compensation for time they spent undergoing mandatory temperature checks as a precaution during the pandemic.

The Merchant of Tennis Inc., which operates retail tennis stores in the U.S., has been allegedly underpaying workers at its facility in San Bernardino, California, the overtime wages to which they’re entitled and made the workers undergo temperature checks while they were off the clock, according to the complaint filed earlier this month by one of its employees.

And back in June, Converse reached a $1.87 million settlement to resolve claims that it failed to pay workers for time they spent clearing post-shift security checks.
