The case study presents a scenario where Paul MacBarrel, a sales team member, is up for promotion despite having close relationships with several top-performing salespeople. Mike Replica proposes four ideas to improve the sales team's performance: introducing a commission-based payment system, dismissing poor performers and replacing them with stronger ones, requiring regular medical checks to ensure fitness levels, and promoting innovative ideas like Paul MacBarrel. The assignment requires students to critically examine the legal risks associated with these proposals (LO2 & LO3), discuss defences available for ABC Ltd if an employee brings a tribunal case (LO2 & LO3), and evaluate employment relations issues that could result from implementing these changes within the organization (LO1).
