Under the Equal Employment Opportunity Commission's (EEOC) guidelines, the four-fifths (4/5) rule is used to determine whether:

AAn employer has met its minimum hiring quota for protected groups
BA selection rate for any group is less than 80% of the rate for the group with the highest selection rate, indicating possible adverse impact
C80% pay disparities between men and women are legally justified
DAn employee has worked at least four-fifths of the scheduled work hours required for promotion

The four-fifths rule is an EEOC guideline that helps determine if a selection process adversely impacts protected groups by assessing if their selection rate is below 80% of the highest rate. It serves as a critical tool in identifying potential discrimination in hiring practices. Compliance with this rule is essential for maintaining fair employment practices.

Understanding the Four-Fifths Rule

The four-fifths (4/5) rule is a guideline set forth by the Equal Employment Opportunity Commission (EEOC) to assess whether a selection process has a potentially adverse impact on a protected group. Specifically, it indicates that if the selection rate for any group is less than 80% of the rate for the group with the highest selection rate, this may suggest a discriminatory effect in hiring practices.

Application of the Four-Fifths Rule

For example, if an employer hires 100 applicants out of 200 from a non-protected group, the selection rate is 50%. If the employer then hires 30 out of 100 applicants from a protected group, the selection rate is 30%. Here, the selection rate for the protected group is only 60% of the 50% selection rate for the non-protected group (30 is 60% of 50), which is below the 80% threshold. This discrepancy could indicate potential adverse impact.

Importance of the Four-Fifths Rule

The significance of the four-fifths rule lies in its ability to identify and potentially rectify discrimination in hiring, ensuring that all groups have a fair opportunity in the employment process. It does not, however, dictate the legality of a company's overall hiring or pay practices, but serves as a tool for analysis and compliance.
