Only California would expect an employer to pay someone else's employees. This is from the law firm of Epstein Beker & Green:
On October 14, 2017, California Governor Jerry Brown signed Assembly Bill 1701, which will make general contractors liable for their subcontractors’ employees’ unpaid wages if the subcontractor fails to pay wages due. The new law will go into effect on January 1, 2018.
Specifically, section 218.7 has been added to the Labor Code. Subdivision (a)(1) provides the following:For contracts entered into on or after January 1, 2018, a direct contractor making or taking a contract in the state for the erection, construction, alteration, or repair of a building, structure, or other private work, shall assume, and is liable for, any debt owed to a wage claimant or third party on the wage claimant’s behalf, incurred by a subcontractor at any tier acting under, by, or for the direct contractor for the wage claimant’s performance of labor included in the subject of the contract between the direct contractor and the owner.Under section 218.7, the direct contractor’s liability will extend only to any unpaid wage, fringe benefit or other benefit payments or contributions – including interest – but will not extend to penalties or liquidated damages.
Section 218.7 makes clear that nothing in it “shall be construed to impose liability on a direct contractor for anything other than unpaid wages and fringe or other benefit payments or contributions including interest owed.”
Notably, employees will not have standing to enforce section 218.7 on their own. That is, AB 1701 gives the California Labor Commissioner, labor-management cooperation committees, and unions the right to bring an action against the direct contractor, but it does not provide any private right of action to potentially unpaid employees themselves to bring a claim against the direct contractor for unpaid wages.
For labor-management cooperation committees and unions who prevail in an action against a direct contractor for unpaid wages, they will be entitled to their reasonable attorney’s fees and costs, including expert witness fees.
For judgments rendered against direct contractors, their property may be attached to satisfy judgment. ...
