If they know a delay is going to last an extended period, maybe they can pull in a few more, but many of us should think about how many of us would be able to jump up and go to work on our day off if our employer called.
Unfortunately providing really good resilience probably involves paying some drivers to be on call.
This is also a good reason to schedule a moderately excessive amount of service — if you need to cover a problem, lower traffic routes elsewhere can drop from every 5 minutes to every 10 minutes, for example. Also a good reason
This reminds me of a student project I once saw about providing transit within UW campus. If I recall correctly they proposed having a bus do a loop around campus a couple of times an hour, and costed it using averages of how expensive it is to run a bus for a certain period of time. The grader quite severely criticized them for implicitly assuming they could find drivers who would be willing to alternate 15 minute work periods with 15 minute unpaid periods all day.
