Tourism is back in the U.S. — but hotel workers are not.

Hotels and resorts learned to operate with leaner staffing models during the pandemic. Three years later, COVID-era Band- Aids like self-service kiosks and less frequent housekeeping have now become the new normal for many firms seeking to cope with rising labor costs and perpetual vacancies.

While employment in a variety of industries has surpassed 2020 levels, the accommodation industry currently employs about 238,000 fewer workers than before the health crisis — a hole that’s likely to persist.

Companies are seeing these initiatives “as a solution to the efficiency issues,” said Alexi Khajavi, president for hospitality, travel and wellness at Questex, an information services firm. But there’s “also just simply the fact that they don’t think that the labor issues are going to be fixed anytime soon.”

Nowhere in the U.S. is the fallout more apparent than in Las Vegas, where 25% of people are employed in the leisure and hospitality sector.

Despite job growth in other industries, there’s a shortfall of more than 17,000 in the city’s accommodation industry. As a result, the unemployment rate is still at 6.1%, the highest among any major metropolitan area in the country.

Technology is on full display across Las Vegas. Major hotels allow guests to access their rooms without much human interaction with self check-in and mobile entry. Drink-dispensing machines are mixing up cocktails at resorts like the MGM Grand. And robots named Elvis and Priscilla are making room deliveries at Marriott International’s Renaissance.

The distrust toward new technologies and cost-saving measures could ultimately help spark the Culinary Workers Union’s first citywide strike in almost four decades.

Contracts covering 40,000 union members just expired, and a strike vote is scheduled for this week.

As drink-dispensing machines have gained ground in recent years, Holly Lang, 45, has seen close to 20 bartenders look for new jobs.

Starting at about $40,000, companies can get one of Smart Bar USA’s automated dispensing machines fully installed, and its employees trained to use it.

The machines can dispense drinks quickly, with the help of fewer bartenders. But Lang, a unionized server who has been working at MGM Grand for nearly two decades, said the new technology requires her to balance more tasks. Machines can get clogged or don’t process the orders she puts in, putting her in a tough spot with customers, she said.

“We’ve kind of had to take on the role of bartending even though that wasn’t something that we actually signed up for,” said Lang.

The service robotics industry is projected to reach $216 billion in 2030 as staffing shortages accelerate the need for automating processes like customer service and cleaning, according to the research company GlobalData.

Smart Bar comanaging member Barry Fieldman said his products weren’t developed to replace workers but to make their jobs easier. Bartenders can make more drinks, earning more money for themselves and the business. It’s “a win-win proposition,” he said.

Recent cyberattacks at MGM Resorts International and Caesars Entertainment show how technological advancements can also come with new challenges. The attack disrupted MGM’s websites, its reservations and payments systems as well as some slot machines at its casinos.

Many hotels, however, are just providing fewer guest services, whether that’s less frequent housekeeping or reduced operating hours for the front desk, bar and pool. More than 25% of hotel operators said the front-office function would be phased out of their properties within the next five years, according to a recent survey.

From dockworkers to screenwriters, employees have long fought to make sure that new technologies and cost-saving practices are not introduced at the expense of their jobs. On Sept. 15 the United Auto Workers launched a strike against the nation’s three largest automakers. Though the pandemic warranted a new approach for hotels, worker animosity has escalated as these policies have endured.

“Companies — not just here in Vegas, but across the country — are capitalizing on the pandemic,” said Ted Pappageorge, secretarytreasurer at the culinary union.

Nationally, many hotels say they have been trying to increase head count. They just haven’t had much luck. A May survey by the American Hotel & Lodging Association showed 82% of hotels were experiencing staffing shortages, most notably in housekeeping.

“Those are numbers we never saw pre-pandemic,” said AHLA Chief Executive Chip Rogers.

Hotels also see initiatives like digital customer service and flexible housekeeping schedules as a way to improve the guest experience.

“Technology’s not going anywhere, and I think that has been a great benefit,” Rogers said.

For those who lost their jobs in recent years, it can be hard to find one with similar pay and skill level in the increasingly diversifying Las Vegas economy. Just 25% of the city’s adults have a college degree, and recent job creation in sectors like health care and manufacturing has emphasized the skills gap.

MGM, the largest employer in Nevada, illustrates some of the nuance of lingering staffing shortages.

The company is on track for another record recruiting year after hiring more than 22,000 workers last year, but workers don’t stay on the job for long, said Rebecca Smith, vice president of talent acquisition at MGM.

Three years after the worst of the COVID-era worker shortages, and MGM still has “mass numbers that we need to fill at all times,” she said.

Looking ahead, there is hope for a pickup in accommodation employment.

Customer satisfaction is oftentimes directly linked to staffing levels, and new hotels — like the one Fontainebleau is opening later this year in Las Vegas — will offer thousands of fresh job opportunities.

Mark Tricano, president of Fontainebleau Las Vegas, said the hotel has received more than 45,000 applications for the roughly 240 positions it had posted.
