SANTA ROSA, Calif. (AP) — Temporary farmworkers will have more legal protections against employer retaliation, unsafe working conditions, illegal recruitment practices and other abuses under a Labor Department rule announced Friday.

Each year about 300,000 immigrants, mostly from Mexico, take seasonal jobs on U.S. farms. The new rule, which takes effect June 28, will target abuses experienced by workers under the H-2A program that undermine fair labor standards for all farmworkers.

Labor Secretary Julie Su said the rule aims to “breathe life” into existing worker protections.

“Our rule is meant to give H2-A workers more ability to advocate for themselves, to speak up when they experience labor law abuses,” Su said at a vineyard in Santa Rosa, north of San Francisco.

The Biden administration announced a proposal for the new rule in September, saying it would boost safety requirements on farms and raise transparency around how such workers are recruited, to combat human trafficking.
