Before handing money to those adjunct professors they need to institute a review and quality control process. There's at least one who has been there for years yet students cannot understand his heavily accented English and another professor in the department has set up free tutoring programs for that professor's struggling students. Another cancels class because she has a meeting at one of her other jobs, but she's not actually teaching the subject of the class when she is there. Complaints to the dean fall on deaf ears.

There are some excellent professors, but the quality of others is horrible and  needs to be addressed before awarding bigger paychecks just because they need more money.
