NEW YORK: As Covid-19 vaccination drives get into gear across the United States, some businesses are offering transportation, paid time off and bonuses of up to $500 to encourage workers to get the jab.

Labor-intensive industries like slaughterhouses, supermarkets and farms, whose workers are at higher risk of contracting the virus, have taken the lead, with several large grocery chains offering two to four hours paid leave time for employees to get vaccinated.

"Providing accommodations so employees can receive this critical vaccine is one more way we can support them and eliminate the need to choose between earning their wages and protecting their well-being," Jason Hart, CEO of supermarket chain Aldi, said in January.

Others have taken advantage of Centers for Disease Control and Prevention regulations that allow them to set up their own vaccination centers.

California-based Bolthouse Farms, which sells carrots, smoothies and juices, holds weekly immunization sessions at its main site and pays $500 to all full-time employees who accept the shot.

Meat giant JBS is offering $100 to vaccinated employees and has distributed materials in several languages to emphasize the safety and effectiveness of immunization. By mid-March, about a third of its 60,000 employees had received a first dose.
