I hate working with immigrants. Does this make me a bad person?

I work at a daycare. On an average day, we have 10-15 children ages 6 months to 4 years. There are three other staff members working there, four including me. Two of the ladies are fairly new to Canada. They came from India not too long ago. I am having a very hard time working with them. First of all, neither of them speak very good english. It's hard for Kelsie (my other english-speaking co-worker) and I to explain things to them. They have a very hard time communicating with the kids, because half the time they don't know what the kids are saying and most of the time the kids have absolutely no idea what they're saying. They can't pronounce a lot of the kids' names correctly, so if they try calling someone by name the kid won't respond. Kelsie and I pretty much have to do EVERYTHING, because when you're working with children, communication skills are extremely important. We have to do ALL the disciplining, because we can speak firm and clear enough for the kids to understand. For example, if one child takes a toy away from another child and it causes a fight, only the two of us can tell them "No, you don't take toys, that's not nice, please give it back" in a way that the kids will understand. If the other ladies were to handle the situation, they'll say "give back, must to be kind and play appropriate" in broken english...kids just don't respond to that. Especially not ones that are just learning to talk themselves. When a parent comes to drop of a child, most of the time they'll have specific things to tell us, make us aware of, show us, etc. Kelsie and I have to always deal with the parents ourselves, because the other ladies won't understand most of what they're telling us. One day we had a new kid come and his mom told one of the Indian ladies he's allergic to strawberries. I was busy dealing with something else but thank god I was listening in on that conversation too because what's the first thing she did at snack time? Give the little boy strawberries because she didn't understand what his mom was saying when she dropped him off. I was able to catch it JUST before he put the strawberry in his mouth and had to explain to her "he's allergic to strawberries...he can not have strawberries!" I could go on and on...

Anyway, does it make me a bad person because I would rather work with english speaking people? I completely understand that immigrants need jobs and I'm not at all saying that they shouldn't be hired. I would normally think it's totally cool that a daycare would have a multicultural staff, and yes I think that young children being exposed to different cultures and races is a very good thing. It's just that it's extremely hard to work them with, given our faced-paced, always-on-the-go, have to have eyes in the back of your head type of work environment. With kids, especially so many really young ones, there usually isn't a whole lot of time to spend explaining things to people who don't understand anything you're saying.

Btw, yes I have talked to me boss. At this point, there's nothing she's willing to do. Hiring immigrants and having a multicultural daycare is more important to her than making sure all her employees are able to do their share of the work. I'm not sure if it makes me a bad person, but I hate the fact that there are 4 daycare providers technically, but only 2 that are able to pull their weight. I'm sick of having to do my job AND their job. Is that wrong of me?
