If a store manager only hires shift supervisors who have a four-year college degree, even though experienced cashiers without a four-year degree can be excellent supervisors, may be occurring.

Bias may be occurring. Bias is basically thinking someone is better than another person due to one factor, without even knowing the person. In this instance, the store manager is only hiring shift supervisors who have a degree, rather than an experienced cashier without a degree. The bias here is dependent on the employee's educational history. The manager may think that even though the cashiers are great, they still may not have the qualifications that one would pick up in college.
