Maybe I was wrong to focus on employer controlled vs real unions. That's certainly a problem, but as you point out it's not the only problem. Here's the broader point I was trying to make: Mexico has a problem with corrupt unions. But US unions are trying to help Mexicans solve that problem, not abandoning cooperation with anyone in the country. I'm not sure if the US teachers union specifically is involved. They'd have less incentive to be because you can't replace a US teacher with a Mexican one.
