Definitions
Manual, repetitive, automatable work required to run a production service. Google's SRE philosophy dictates that no more than 50% of an SRE's time should be spent on toil — the rest should be engineering to eliminate it.
In plain English: Boring, repetitive work that keeps systems running but could (and should) be automated — the chores of the tech world.
