In Anna Karenina (2012), one evening, Levin settled down after mowing crops along with a group of mowers, and Theodore met him:
Levin: How many mowers is it, Theodore?
Theodore: Forty-two, Master. In your father's time, it was work for two days for 30 men. Though he never picked up a scythe himself.
Levin: The men don't like me for it.
What does "for it" mean ?
