I have a personal Google calendar, associated with my own personal Google account, and a work Google calendar, as part of my office's Google Apps setup. Whenever co-workers of mine try to schedule appointments with me, they don't see my personal calendar show up as "busy" times. I've been able to share my personal calendar with my work account, and I can see the calendar there and view appointments, but none of my personal appointments appear as busy times when a co-worker tries to schedule an appointment. Is there a way to set this up?
Both your calendars are distinct, even if your personal calendar is shared with your Google Apps account.
Unfortunately, there is no native way to share a common busy/available status merged from 2 calendars with your co-workers.

I think only a free/busy consolidated calendar will work for you. You could create yet another additional calendar just for this purpose and copy all events to it though not really practical so I think only an introduced feature "all calendars as one" in Gcal could cater for this.
Here are 4 workarounds: None of them are perfect, but they can fulfill your requirement : to make sure your coworkers don't schedule a meeting in your PRO calendar when you are busy in your PERSONAL calendar.
Share your personal calendar with your coworkers, and teach them how to look at your availability in both your calendars. (quite tedious, and practically unusable if many co-workers)
Each time you create a new event in your personal calendar, duplicate the free/busy status by inviting your GoogleApps account to the event. The easiest way.
Sync automatically both calendars, with Google App Script , or using a third-party service. Eg : https://syncthemcalendars.com
Publish both calendars in a schedule service , like https://calendly.com/ , that can expose several calendars at the same time, so your coworkers pick a schedule in it instead of calendar. Not very practical for internal use, but efficient for exposing availability to an external user.
After trying everything, here is the answer. This is the only way I could find a way to have my personal google calendar show up on my business google suite / workplace calendar so all my employees could see that I was busy without needed to subscribe to a separate personal calendar (which I tried and everyone just checked my work calendar and scheduled meetings over my personal calendar).
This app, SynchThemCalendars let me first identify my target work calendar and then identify my source personal calendar. I logged into each using Google Sign in and it auto-synced. Once they were in sync, I was able to modify what information the personal calendar showed on my work calendar... so I set the description to be overridden with "BUSY", made it private, and hid all remaining details. You just hit the drop downs and confirm by clicking the checkmark. Couldn't have been easier. I then checked my Google Suite work calendar and where all my personal google calendar events were, it simply read busy.
I can now use my Calendly off of one calendar and have my employees just check my one work calendar and see my full availability (and unavailability) all in one place. So stoked!
Previously I had my executive assistant manually adding "Busy" next to each personal event so employees would stop scheduling meetings over my personal events. Service came with a 14-day trial. I was so excited that it all worked, I just signed up. You can pay monthly for like five bucks or I chose yearly for $4/mo for $48 total. Game-changing.
