Can my employer see my personal calendar synced with Google calendar?

This might not be the correct subreddit so if someone can link me to the right place I'd appreciate that.

Anyway:

Even though it's ironic that I use Google Calendar and that I'm asking about privacy, I have a question about it. I want to sync my personal Google calendar into my work GSuite calendar. But I want to be sure my employer cannot see my data. So my question is, what level of privacy does GSuite provide to employees …
