1. Write To Your Favorite Companies
Let them know that you intend to hold off on buying their products or services until they hire American.
2. Publicly Embarrass Them On Twitter
Most corporations monitor twitter. If you don’t have time to write a letter, tweet every now and then to let them know that they should do their part by hiring American.
3. Buy American
If company X doesn’t hire American, buy a competing product from a company that does. Businesses respond to market pressure, so feel free to vote with your dollars.
