Dean Jones says:

"Teaching in the summer shouldn't be a 'deal breaker' but if you insist on only teaching two sessions without budging much on the enrollment, it could become an obstacle to an agreement."

Your response:

1.  OK. I'll accept twice as many students in my two summer school classes.

2.  Upon reflection, I'm unwilling to go up much...Maybe 15%, but that is as high as I can go...

3.  Can't you find an adjunct to teach the summer sessions?  I would think that there would be lots of qualified people -- retired college professors or managers in the community --  who are looking to pick up some extra income by teaching an undergraduate business course.  By contrast, my skills are not easily replaced and my time is more valuable to the college as a researcher.  Don't you agree?

4.  Given my background in the graduate student organization, don't you think it would be better if I used my first summer to get involved in service activities, such as welcoming other new hires to our campus?  Such orientation activities could really lower turnover and would improve long-term morale in the college.  Don't you agree?
