I think if I were a diligent student (I wasn't - like you I would have reveled in doing next to nothing) or a concerned parent I'd be worried about the disruption caused to the classes (and students) they taught.
One of the Humanities teachers at my school has also left, but for Middlesbrough to be Head of RE (previously an RE teacher).
Basically, from what he told me (didn't teach me, but we spoke regularly as we were on the Germany trip together) - he said if the job was ever there for him, he'd take it if it meant furthering his career.
