Arrest ALL employers who hire illegals. They will leave on their own. I have a company going to put a roof on my house this week. I asked if there were any illegals involved. The guy gave me documentation (I’m not a documentation expert) and ensured me he couldn’t get insurance or a contractors license in PA if he did hire illegals. He may be lying but I did make my point. I also rejected two Union roofers who told me I must be racist.
Good!
If you use hotels/motels, make a point of asking there, too.
There are many pressure points we can use effectively.
The company I worked for back in the 90s was not so diligent when they hired a roofer for a hot tar job. One morning, the crew had just got started and a bunch of federal cars/vans pulled into the parking lot, called them all off the roof, and carted them away. The roofer had another crew on the job that afternoon that looked just like the crew that got carted away.
