Under Lab. Code 2810.3, an outsourcing employer is liable for employees’ wages for work done for another entity if the work is within the outsourcer’s usual course of business. Here, the court holds that the section did not apply to defendants which were corporations that bought produce from farming corporations for which the workers were employed. While the defendants’ produce cooling sheds were near the farms on which the workers grew the crops, growing crops was not within the defendant corporations’ usual course of business, so they were not liable for the wages that the farmers failed to pay before going out of business.
