This DOL web page explains basic requirements, employee rights and other information regarding the H2B temp visa which states that early termination requires the employer pay return transportation costs.
OTOH, under the the H2A ag worker temp visa there is a provision called the 3/4 rule that requires the employer to pay the early terminated guest worker 3/4 of the wages the worker would have earned thru the life of the contract.
I have no problem with them being paid what they are entitled to under their contract. They shouldn’t be cheated. I do have a problem with them staying in the US after their employment has ended, and I have a problem with the way H2B is written for several different reasons.
Pretty cut and dry...They get bus fare to get back home.
