underhanded

Use the adjective underhanded to describe someone who plays dirty tricks, like a cheating poker player or a manipulative classmate.

It would be underhanded to spread gossip about your opponent during a student council election, just as it's underhanded for a business owner to pay herself more while laying off workers.
