Liability protection with day laborers

[Daniel Mina]

How do investors protect themselves from the liability of day laborer work? I live in TX and we have access to a lot of laborers who are undocumented uninsured immigrants who are trying to feed themselves and their families. If one if these guys falls off the roof or has an anaphylactic reaction to some building material, how do I make sure I'm protected? Is this covered under umbrella insurance? Do I need to get separate workman's comp? Do signed waivers hold any weight? Yes, I know you're not a lawyer and not giving me personal legal advice... just looking for general answers here. Thanks
