This can be problematic if your work calendars can only be shared with Free/Busy information, and you are not participating in a Bring Your Own Device (BYOD) program with your company. There’s one set of calendars, however, that do not sync to all devices, and that’s delegated availability-only (Free/Busy) calendars from Google. Generally, this works well, and all of my directly connected accounts sync fine across the Calendar on macOS, iOS, and iPadOS. I use Apple’s Calendar app to view and manage my calendars in iCloud and Google. This post explains how you can sync Free/Busy events from delegated Google calendars to the Apple Calendar app in iOS and iPadOS.
