pay per class-not hour, and more

I wish this site would require job posters to mention the number of classes one must teach instead of just listing hours as this is misleading. There are alwasy public school jobs posted on here starting at 12:40 for 4 hours at 30 per hour but you are actually teaching 5 classes so you are making less than 25 per class. This at a public school in 2010? This is terrible pay. If I saw this I would not even bother sending out a text and so on but... Manager, can you please require people to mention the following info:

 

The location

The start and finish time

The number of classes

The pay per class/or hour

REFERENCES so we can find out more about the school...schools get resumes and so on so why should we never get info about the school. You do not allow us to post about poor jobs on here so crappy schools just keep on rolling along while teachers get put through the ringer so why not allow us to know more about what the school is?

I know they dont want to mention the school as people would just cut out the recruiter, as we should do anyway, but we should be able to know more about our perspective employers I think. Just my opinion. Cheers.
