What are the elements of public personnel administration and how do they differ from their private sector counterparts?

Public personnel administration involves elements such as recruitment, training, performance evaluation, and employee relations within government agencies. It differs from the private sector primarily in its emphasis on compliance with regulations, accountability to the public, and transparency, as well as a focus on serving the public interest rather than profit maximization. Additionally, public sector employees often face more rigid structures and job security due to civil service protections, while private sector personnel may have more flexibility in hiring and firing practices.
