Companies are putting their foot down when it comes to COVID.

With the highly contagious Delta variant sweeping across the country—and only about half of Americans fully vaccinated—a big wrench has been tossed into many companies’ fall plans to return to the office.

More of them are moving beyond offering incentives like water bottles, T-shirts, and cash bonuses—and have started requiring that their staffers get a COVID shot. In the first two weeks of August, a host of airlines, retailers, tech companies, banks, and health care companies have told employees that vaccinations will no longer be optional to come into the office—or in some cases, like at Ascension Health, even to work remotely. Some companies have more forgiving terms than others, by offering employees the option to keep working from home, rather than risk termination. Requiring vaccines is a move that most workers support (52% according to a recent Gallup poll), but a sizable chunk of the workforce (29%) is strongly opposed—likely some of the same people who are strongly opposed to the COVID vaccines in general.

Here’s a running list of the major U.S. corporations that have made moves to get their staff vaccinated, and the policies they’ve put in place.
