They can stay home and then go back to Mexico.
If they take the day off, then the employer has every right to assume that they quit.
There will be another 10 Mexicans looking for that same job the next day.
Y'know, if they didn't have this pissy attitude and wore a bit of humility about this great country, I would not be as mad at them as I am. But, to come here illegally and tell us to go pound sand, is a bit too much for me. So, EF 'EM!
