Research from UKG estimates that the World Cup, which runs from June 11 to July 19, could cost global employers some US$17 billion in lost productivity, with 37% of workers planning to adjust their schedule because of the tournament.

The survey found 27% of employees are likely to miss work by showing up late, leaving early or skipping entirely, while 11% admitted they would work while hungover and 14% said they would secretly stream matches and highlights while on the clock.

UKG, an AI platform for HR, pay, and workforce management, surveyed 8,000 employees across Australia, Canada, France, Germany, Mexico, the Netherlands, Britain and the US to assess the World Cup’s impact on workplaces.

This year’s expanded tournament, co-hosted by the US, Canada and Mexico, will feature 48 nations and 104 games.

The tournament could lead to some US$11.7 billion in lost productivity costs in the US alone, with Germany next at US$1.34 billion, according to UKG.

“When absenteeism and presenteeism hit at scale, the effect is immediate and expensive,” said Suresh Vittal, chief product officer at UKG. “Productivity drops, customer experience suffers, and morale takes a hit as the rest of the team is left to cover the gaps.”

And managers are not immune to the lure of a mouthwatering match-up. The survey found 42% of managers would likely plan a day off and 45% ask for last-minute flexibility.
