I am not going to weigh in on any particular job, but obviously the data show that as a class of employees women have been underpaid significantly for equivalent work and while it has improved that is still the case. The problem is to take that generally accepted fact and apply it to any specific person or job. So stating the fact that a general trend exists therefore in this specific instance that trend is also present is bad logic and legally meaningless.
It is also a problem in a merger situation of two unequal parts to assume that one is being unfairly treated - happens all the time in all segments of society - Company A mergers with company B and 80% of the cuts happen to company B's workforce is a standard occurrence. Just because one is focused on women and the other men does not signify anything. Specific to this merger of athletics at TN, the income and profitability of the football and men's basketball programs suggest that their operating budgets are much larger than other sports, they have probably been able to afford more staff and may have been able to attract more qualified employees with higher salaries. It would not be surprising to discover on a pure numbers basis that more of the staff associated with these two programs were maintained than for any of the other sports men's or women's. And given the possible higher quality overall, it wouldn't be surprising if the percentage retention wasn't also higher. None of that has anything to do with gender. The hiring and firing procedure and compensation rate for equally qualified people is a different question.
As for academia having small fiefdoms - I grew up in an academic environment and totally agree, but I also split my professional life between theater and business and saw just as many fiefdoms in those professions (if not more.) There are very few true democracies in any walk of life - the best you hope for is benevolent dictatorships. Almost all 'departments' in all professions have a bias towards some aspect of their work and that bias affects the prospects of those hired or applying for inclusion - in academia in may be proponents of a specific 'school of thought', in the arts a specific artistic 'movement', in business a specific 'management school'.
And I have a higher opinion of the US legal system in terms of its equality. I agree that there is a bias built in based on the quality of representation, and there are other disturbing trends, but a bias towards institutions over individuals ...? The burden of proof is always with the accuser and legal proof is difficult to obtain. But just because someone is seen as the 'underdog' should not have any bearing and generally doesn't.
We have experienced with our beloved coach the annoyance of what most feel is a nuisance lawsuit - based on harassment but it could just as easily have been based on discrimination. I am not sure sitting here in CT and reading press releases that what is happening in TN is any different. Employee lawsuits are very expensive to defend and very easy to bring - and at least some of them are baseless and aimed at a quick score. I am not willing to jump either way without a lot more information.
As an aside - we have gone down an interesting path in employment law. We have codified protections for employees based not on actions but on the perception of those actions by the employee.
