I'd like to add a fourth one loosely connected with gender: service and promotion.
The MLA Report "Standing Still: The Associate Professor Survey" says it best: "On average, it takes women from 1 to 3.5 years longer than men to attain the rank of professor, depending on the type of institution in which they are employed and regardless of whether they are single, married, or divorced or have children." According to the survey, women report that they do not spend significantly more time on service than men do, although they spend more time on teaching.
I wonder about this, although all I have is anecdata. Do women really spend the same amount of time on service as their male colleagues, or do they just not count some of the kinds of service that they do perform?
I'm thinking of conversations with colleagues from other institutions who are irritated that "the men" in their departments aren't doing X or Y service task. When I asked them why they didn't give the tasks to "the men" instead of taking those tasks on themselves, they laughed and said, "They wouldn't do it! It would never get done."
My belief is that if "the men" wouldn't do Task X or Y, the department would soon figure it out. Either (1) something would go badly awry in the operations of the department, in which case the faculty member who hadn't done the work would come under scrutiny, or (2) it wasn't worth doing in the first place, in which case the female colleagues should give it up, too. Either way, the colleagues weren't doing either themselves or "the men" any favors by completing these tasks.
Were "the men" really slackers, or were these colleagues just unfairly painting an entire gender with the same "slacker" brush? Did my female colleagues count the extra work that they did as service?
Are the kinds of service that women do different from the kinds of service that men do in departments? Does that service have anything to do with rates of promotion?
