Commitment without ideals
Real teachers know real life ain't like that, so good on researchers for discovering that secondary staff who drifted into the job are just as likely to be fully committed and in challenging schools as their starry-eyed colleagues -and seem less prone to burnout and disillusion.
So, drifters, be proud. If some smartarse interviewer asks about your vocation, tell 'em it's just a job, but you're damn good at it. Accountants don't need a vocation to be excellent - so why should you?
