Businesses in several different industries are rescinding job offers they made just a few months ago, in a sign the tightest labor market in decades may be showing cracks.

Companies including Twitter Inc. , real-estate brokerage Redfin Corp. , and cryptocurrency exchange Coinbase Global Inc. have rescinded offers in recent weeks. Employers in other pockets of the economy are pulling away offers too, including some in insurance, retail marketing, consulting and recruiting services.

At the same time, many companies have signaled a more cautious hiring approach. Netflix Inc. , Peloton Interactive Inc. , Carvana Co. and others announced layoffs. Technology giants such as Facebook parent Meta Platforms Inc. and Uber Technologies warned they will dial back hiring plans.
