This year, over 16 million U.S. employees plan to miss work on Monday after the game between the San Francisco 49ers and Kansas City Chiefs, according to a new survey conducted by the Harris Poll for the Workforce Institute at UKG—a think tank associated with the HR, payroll, and workforce management solutions company. Around 10 million of those workers have already requested the day off, and over 6 million plan to skip but haven’t requested a formal absence. To put that into perspective, that means around 14% of U.S. workers plan to miss at least some work on Monday. 

The cost of those absences can add up for employers. This year has the same number of expected Monday absences as 2021. That year was estimated to cost businesses more than $6 billion in losses, according to HR consulting firm Challenger, Gray, and Christmas, and UKG believes the losses this year will be similar. 

The “Super Bowl flu” extends beyond absences alone—about 28% of workers polled believe they’ll be less productive at work that day, according to the UKG survey. 

Dr. Jarik Conrad, executive director of the Workforce Institute, says that the day after the Super Bowl allows for a diffusion of responsibility among workers who may have otherwise been reluctant to skip work for more esoteric reasons. “This might be a case of safety in numbers,” he tells Fortune. He added that the Super Bowl allows employees to rationalize skipping work by thinking: “I know a whole lot of people are going to do it, then I won’t be isolated, and maybe there won’t be any consequences. They can’t fire everybody.”

Aside from business losses, the “Super Bowl flu” can be hard on other workers. Employees who do show up on Monday may have to take on additional work, Conrad says, and people who are actually sick might be doubted by management. “Folks who are just taking that day off are doing a disservice for those people who might need it for childcare, or their own sicknesses, or whatever legitimate reasons there might be.” 

Bosses can certainly try to crack down on mass absences, but they might find it tough going. Around 37% of U.S. employees believe that post–Super Bowl Monday should be a national holiday, and one in five managers plans to miss at least some work that day, according to the UKG survey. 

For post–Super Bowl Mondays moving forward, businesses can mitigate losses by educating employees on attendance policies and the impact of their absence on other coworkers. Employers can also get creative and plan ways to celebrate the Super Bowl in-office on Mondays to boost morale.

“We’re just going to have to figure out how to work with it instead of working around it,” says Conrad. “Make it a positive thing.”
