Many back injuries and pulled muscles that occur in the workplace are the result of picking up something that is too heavy, not bending the legs, not asking a partner to assist or trying to lift or hold a heavy object above the shoulders.
Pre-elementary teacher education majors had to make do with a starting salary of just $32,400 at this time, while physical education teaching/coaching majors and special education majors took home $40,100 and $42,200 in their first year, respectively.
My wife is an adjunct teacher at a state university. She is paid $3,000 to teach a class that meets twice a week for 15 weeks in Earth Science. That's usually 30 classes divided into $3,000 = $100 per 1 hour 45 minute class.So...he problem isn't that adjunct teachers get paid so little, it is that they work so few hours. I'm full-time at a community college. If your wife taught as many units as I do, paid at the rate you describe, she would be making $30,000 a year, with zero benefits.
