A seed company was held jointly liable for wage violations committed by a labor recruiter who hired migrant workers for detasseling and rogueing work. The court found that because the work was integral to the company's business, performed on its property with its equipment and supervision, the company was a joint employer responsible for wages and working conditions. This matters to construction subcontractors because it shows that general contractors can be held liable for labor law violations by their subs, even if a separate entity recruits and manages workers.
If work is core to your business and happens on your property under your supervision, you may be a joint employer liable for wage violations by labor brokers or subcontractors—even if you didn't directly hire workers.
