It is risk assessment/management.

The non-boring companies I've worked for have had problems of wanting to work you at 150% of your schedule, quite often illegally. It is insanely rare that you'll get a job that keeps you busy (only) 8 hours a day constantly. Either the place is always on fire and has 12 hours of work a day, or you'll have it better managed and work will be bursty with the majority of the time under utilized. Spend that extra time being taught stuff on the company dime.
