I'm not a programmer, so maybe I totally mis understand this, but in most contexts "sprint" would mean I worked extra hours without pay so my employer could make even more money ???
A sprint in agile software development is simply a relatively short time period (a few days to a month) in which a set amount of work is supposed to be finished.
You're probably referring to a 'crunch', although the overtime is (supposed to be) paid.
"Sprint" is a project management term that describes a focused effort on specific goals, not extra work. It could have been extra work for them, but it would be unrelated to the fact that it was a Sprint.
