throwing fits at school

My 5 year old son is throwing fits at school on a daily basses. Im being called every day at work over this.He has his fits when it is time to change from doing one thing to doing something else. He can not get use to change.He throws the fit for hours,I have had to leave work to go to the school.Is there any thing we can do to work with him? Time out punishment nothing seems to work.

Well,  this is the end of November - a time when most kids have gotten thoroughly used to the routine of school.  Has this come up recently,  or has he had these episodes since early September?

I also wonder is school a new experience for him?  Has he been in daycare or pre school?

I don't think I would punish for this.  It sounds like something else is going on.  If he has good use of language and can express himself well, I would ask him quite casually (when you are calm) what is going on.  I think that if it's just the transition from one activity to another, I would be consulting his Dr. as well.
