Hi, Sukhpal
HR (Human Resources): HR means the workforce of an organization. It includes implementing management strategies, policies, labor mobility, recruitment/resourcing/separation, training & development, appraisal, employee welfare/benefits, payroll, competency mapping, etc.
ER (Employee Relations): It is at a macro level. Nowadays, it is a very sensitive and important management aspect. It involves maintaining good employee and employer relationships to contribute to good productivity, morale, motivation, employee development, employee engagement, grievance investigation, meeting statutory and non-statutory compliance for employees, legal compliance, and avoiding disputes/conflicts. We can say ER means maintaining a healthy atmosphere and taking care of the flow of work between the organization and workers.
