Mark Gurman, Bloomberg:

Apple Inc. will begin to force unvaccinated corporate employees to test for Covid-19 each time they want to enter an office, a move that tightens its virus protocols while still stopping short of a vaccine mandate.

The new requirement will also apply to employees who decline to report their vaccination status to Apple, the company told employees this week. Vaccinated staff will be required to take rapid tests once per week.

And:

Apple retail store employees, meanwhile, will have slightly different rules. Unvaccinated staff will be asked to test twice per week instead of each day they come to work. Vaccinated workers will also need to take a rapid test each week.

Slowly but surely, Apple is tightening its vaccine stance, from booting antivax apps from the App Store, to requiring employees to report vaccination status, to these new testing requirements.
