What is the difference between a human resources manager and a trainer?

I personally think what the two people above said is a bit complicated. Human resource managers are professional managers engaged in human resource planning, recruitment and allocation, training and development, performance management, salary and benefit management, etc.

Trainers are under the management of the human resources department. If a company recruits people, they must be arranged by the human resources department and receive at least one month of on-the-job training
