Industrial relations involves managing the relationship between employers and employees. It encompasses phenomena inside and outside the workplace that determine and regulate the employment relationship. Maimunah Aminuddin defines industrial relations as "the relationship between workers and their employers within the work environment." Understanding industrial relations is important for various groups including workers to understand their rights, trade union leaders to effectively represent workers, managers to improve productivity and profitability, lawyers to competently advise clients, and human resources professionals to properly administer the employment system.
