Work Step by Step
a. This may be true because there is a shortage of labor in some areas, so it's hard to find jobs. Another reason may be that people who are good in some fields may be employed in other higher-wage companies. That's why they're avoiding working in college or school. If some school wants to hire them, it has to spend more money than it does for teachers from other fields.
b. Different teaching loads are drawing people with different lifestyles and resources. Some of them may find it attractive to work at a university, no matter how much more money they could earn in some other private company. Also, this could be a way for a university to employ a hard-to - find workforce.
