Schedule changes - again!

I just heard today from my department head that she is going to have to change the special education schedule - for the 3rd time since school started one month ago.

Her reasoning this time is that we have a 'full-time sub' in one of our classes that is doing a poor job and needs to be let go. I completely agree with her sentiment. However, she is most likely going to remove my first period co-teacher, leaving me alone with 20 special needs students. 1 student is deaf, 5 are mildly retarded, 3 have emotional disorders, 3 have behavior disorders, and the other 8 have multiple varieties of learning differences...

Please pray that this doesn't happen. I would give my all to these kids, but it would be very difficult to make sure that ANY learning is going on.
