To critically assess how effective HR systems and policies such as Sickness, Grievance, or Performance Management impact on business operations and practice, the business needs to consider each of these areas individually and then explore how they intersect and influence one another. Sickness Management: Sickness management policies are crucial for maintaining the health and well-being of employees. Effective sickness management systems can reduce absenteeism, increase productivity, and create a positive work environment. By offering sick leave, flexible working arrangements, and access to healthcare services, organizations can support their employees during times of illness. This, in turn, can lead to higher employee morale, lower turnover rates, and improved overall performance (Marchington et al., 2016). Grievance Management: Grievance management policies are designed to address and resolve conflicts or disputes within the workplace. An effective grievance management system provides employees with a mechanism to voice their concerns, ensures fair treatment, and promotes a culture of open communication. By addressing grievances promptly and fairly, organizations can prevent escalation of conflicts, maintain employee trust, and enhance employee engagement. This, in turn, can lead to a more harmonious work environment and improved employee satisfaction. Humanise this please
