Driving the news: The share of job postings on Indeed requiring vaccination has jumped 90% in just the last month.

The big picture: Vaccination rates in the U.S. are climbing, but hesitancy remains high in certain places. And the Delta variant is foiling companies’ return-to-work plans.

Now, it’s not just front-line jobs at restaurants and shops requiring vaccination. Postings for jobs in software development, marketing and sales are mandating that applicants have the shot too.

What’s happening: At the beginning of the year, there were basically zero office jobs asking workers to get the vaccine. But even if workers are 100% remote, they’ll have to come on-site at some point to meet with colleagues — and firms don’t want to take risks.
