To enforce President Joe Biden’s new COVID-19 vaccine regulation, the Labor Department is going to need a lot of help. Yet its Occupational Safety and Health Administration (OSHA) doesn’t have nearly enough workplace safety inspectors to do the job.

The 490-page regulation will cover American businesses with at least 100 workers, or about 84 million employees in all. So the government will rely upon a corps of informers to identify violations of the order: Employees who will presumably be concerned enough to turn in their own employers if their co-workers go unvaccinated or fail to undergo weekly tests to show they’re virus-free.
