What are the two factors that contributed to the development of personnel departments?

The development of personnel departments was primarily influenced by the need for better employee management and the rise of labor laws. As organizations grew and labor forces diversified, it became essential to address employee relations, recruitment, and training systematically. Additionally, the introduction of regulations aimed at protecting workers' rights necessitated specialized departments to ensure compliance and foster a positive work environment. These factors led to the formalization of personnel functions into dedicated departments within organizations.
