Funny you say that. I'm a special education teacher and department chair and I work with paraeducators, also known as teacher's aides. It's a week and a half before school starts and I've been working a week already for this school year, having spent four weeks of the summer teaching summer school to kids who failed the previous year, and one week at an out of town training event.
So much for only working ten months out of the year.*
Two weeks ago, I was staffed up for paraeducators in my department. But our newcomer program was short two bilingual paras, so I lost a new hire that happens to speak Spanish. The district sped department gave us the applicant who was on the bottom of the pile since all the others had been hired. Her interview did not go well. Nice enough lady, but she now works at a day care as a "teacher" with her own classroom. It was obvious that she was not enthused to work with junior high aged kids, nor to be the helper in multiple classrooms instead of running her own.
We'll have to hire her though, if she'll accept the job. The reason that we have a hard time finding paraprofessionals is that they are paid so low, even considering all the time off they get. We get some amazing people for the money we pay, and they do a lot of good. But if we want more of them to help with the surge of migrants, for example, we have to be ready to pay more.
*I know that the image of a teacher is short hours and long vacations. Technically, a teacher is only required to be at school (in my district) 7:35 to 3:35 with a half hour duty-free lunch. But there is no way to do the job of a teacher in seven and a half hours. Not if you care about actually teaching the kids, which 95% strong do care. We end the year three or four days after the kids do and start the next year one to three weeks before the kids show up. We all take trainings in the summer, and those without rich husbands work summer school.
Biggest reason young teachers quit after the first year is that they realize that "the whole summer off" and "short work days" are myths.
