I think the clear simplest thing to say about SIU professors is a majority do the least amount of work possible and still retain some feeling they are not worthless. I'm certainly not saying all of them, but many, many of them are working at a level of effort that would embarrass their Mothers. Certainly, a whole bunch of this is because of SIU's poor management, but as adults the professors need to take some of the blame.
As a taxpayer, we would like to see 40 hours a week out of each SIU employee. So, if you go to work at 8:00 AM and work to 5:00 PM with an hour for lunch, Monday through Friday, that is what we would like to see. I'm all for flex time too, work any 40 hours you like, but do work them. I know I'm about to hear from a bunch of professors that we are working more than 40 hours a week, "way more buddy!" In the real world, we don't count the time you are having a walk as work, nor digging your garden, cooking dinner, doing boy scouts, or sleeping. We are thinking about work all the time too and we don't get paid for sleeping either.
A reasonable argument might be that you only work 20 hours a week, but get results as good as someone "who is less special" working 40 hours. My argument back is we are paying you a salary and the way for the taxpayers to get ahead is if the best performers work the full days and perform much better than average. Does anyone want to argue that a professor who applies his rear to the chair and his fingers to the keyboard for 2000 hours per year is going to be more productive than one who does the same for only 500 hours?
It looks like professors have the best jobs of anyone in American (except for Software Engineers, who everyone knows are the coolest. Here is a link to Money's list of best jobs.) and this is very clear from the outside.
This little trick about "working at home," (wink, wink) even though you have a private office with a door? Do you think that anyone is buying that crap?
If you were wondering what the taxpayers who might give universities more money see, now you know.
I hope this doesn't hurt to many egos, but the SIU professors are really smart and you aren't fooling anyone.
