I does not always work out that smoothly. The general Contractor (GC), the jefe, will hire an Hispanic sub for tasks likes drywalling and tiling. The sub will then hire illegals, who will do a hit or miss job. The GC will then hold back some of the payments and ask for unpaid change orders. The sub is now struck, unable to pay for its materials, the suppliers file liens, causing the GC to hold back more money. Then, wage-hour attorneys will get one of the workers as a client and file suit. While the worker may ony get a few thousand in damages, the attorney is entitled to court-awarded fees often reaching into the hundreds of thousands of dollars.
I have seen this happen many times, both in the construction and restaurant industries.
“The sub will then hire illegals, who will do a hit or miss job.”
The sub typically has people he employs on a long-term basis. Most if not all of his people worked together with him as employees, often for a few years. The sub generally has sufficient skills, both for the trade and in English.
If a hombre gets sick, a primo(cousin) o hermano(brother) might get called in. The sub is on the job and keeping watch. The newcomer will only be doing non-critical work or working with an experienced hombre.
The only significant problems I’ve seen using invaders is in HVAC work.
One of the biggest problems is that the whole illegal labor market encourages an entire host of illegalities, safety violations, and shoddy work, in addition to the illegal hiring and tax fraud.
