Why so many hotel workers are going on strike.

From Marketplace, I'm Sabrie Ben Ashore, in for David Brancaccio.

Strikes are continuing today at several large hotel chains.

More than 10,000 hotel workers went on strike over the holiday weekend in nine cities,

including Baltimore, San Francisco, Boston, Honolulu.

Workers are demanding higher pay, adjusted workloads, and return to some pre- Pandemic conditions.

Marketplace's Henry Epp has more.

When pandemic lockdown's upended the travel industry, many hotel companies cut back their staffing and stopped offering

some services like daily room cleaning. The Unite Here Union, which represents many hotel workers,

says that some companies never brought those services back and didn't rehire enough

staff after the pandemic subsided, even as travelers returned to hotels.

The union says that's caused some workers to lose jobs in income and left remaining

hotel employees to pick up heavier workloads. So far contract negotiations

between the Union and hotel chains have been unsuccessful. Both Hyatt and Hilton have said they're willing to continue

negotiations, according to media reports. Marriott has not publicly commented. Strikes over the weekend

were scheduled to wrap up today, though the union said workers in additional cities have also authorized walkouts.

Last year, hotel workers won new contracts in Los Angeles and at casinos in Detroit, where workers were on strike for 47 days.

Labor Day marked the unofficial end to the busiest summer air travel season on record.

On average 2.7 million people passed through TSA screening each day this summer.

All of those travelers depend on air traffic controllers.

These are the people who keep planes safely separated from each other.
