I didn’t know that professors were union. I thought they were professionals.
Relatively few faculty have collective bargaining. Most faculty labor cartels have little power.
The demands of this labor cartel are ridiculous, just laughable. Faculty labor markets for most disciplines are very tight. For business faculty, labor markets used to be very good. Faculty with good qualifications could move with ease usually at increased salaries. Those days have faded however starting with the dot com bust. In my discipline (information systems), the labor market is absolutely terrible now.
Universities should reduce faculty compensation, not increase it. Faculty have been able to bid up their compensation in the good times. Now the reverse should occur. If a faculty cannot demonstrate labor market demand, compensation should be reduced. It is an odd situation for never ending tuition increases funding high faculty salaries (as well as high salaries of other university personnel).
