Not so! I used to drive a 911 ambulance. We we're told to drive safe and not break various rules, but were punished when we didn't arrive in the allotted timeframe of 9min. The punishment was that workers on 24-hour shifts (who normally had a house to sleep in) were forced to post on street corners and not allowed into their quarters. This made the shift miserable and the lack of sleep was a real safety problem.
