If we take a brief look at the developments in the HR/IR scenario, it initially started with slave and master relationships, then evolved into serf and master dynamics. With the recognition of the human factor, it transformed into the employer-employee relationship. Over time, the human element has gained increasing importance, and human resources are now considered the most valuable resource in any organization.
HR functions span from recruitment to retirement, including processes such as selection, recruitment, induction, training and development, wage and salary administration, time office management, performance appraisals, awards and rewards, incentive schemes, disciplinary matters, statutory compliance, handling employee grievances, managing industrial disputes, strikes and lock-outs, dealing with collectives and collective bargaining, liaison with statutory authorities, separation of employees, and conducting exit interviews.
The HR department is responsible for forming HR policies and ensuring uniform implementation by coordinating with functional heads. These functions are now categorized as HR and IR functions. Functions like handling industrial disputes, strikes, lockouts, grievance handling, time office management, statutory compliance, and liaison with authorities are classified as IR functions, while the remainder are considered HR functions.
