Four years without taking a vacation...

Staff shortage at prevous employer

1. Speculative work

2. On back up

3. Go on vacation

4. Autoupload resolved ticketed work

5. Parse text messages to your phone for keywords: "reversion", "bug", "backup"

6. Rollback in case of any and autosend text message "working on patch"

7. Continue vacation

8. Return to work and write patch. Roll out changes as before.

9. Rinse and repeat.

Is this legal in Australia?

No wonder they have staff shortage if there's no vacation. Actually it's a miracle they have staff at all.
