Eileen, a $52-$year$-$old employee with $34$ years on the job, was terminated by Rocket Co$.$ during a reduction in force, while her $41-$year$-$old co$-$worker, Kimberly, was retained. The company used a $$Redeployment Selection Process $($RSP$)$ to determine which employee would be terminated and which would be retained. Using the RPS$,$ the supervisor compared the performance of employees on nine criteria, rating them on each with a $1-5$ scale. Eileen received a cumulative score of $17,$ while Kimberly scored $39.$ The supervisor eliminated from the final scores the one criterion on which Eileen received a perfect $5.$ In Eileen$$s regular performance appraisal conducted earlier that year, the same supervisor said Eileen was $$doing a great job.$$ Eileen sued, challenging her termination. On what basis can Eileen challenge her termination? What arguments can Rocket Co$.$ make in its defense? Who has the better argument?
