Step 1: Understand internal sources of recruitment.
Internal recruitment means filling vacant positions from within the existing pool of employees of the organization, rather than looking for candidates outside. Two key methods are transfers and promotions.
Step 2: Explain Transfers.
A transfer involves shifting an employee from one job to another, from one department to another, or from one shift or location to another. Importantly, a transfer is a horizontal movement - it does not typically involve a change in the level of responsibility, status, or pay. Transfers help in training employees for varied roles and give the organization flexibility in deploying its workforce.
Step 3: Explain Promotions.
A promotion involves moving an employee to a higher position that carries greater responsibilities, a higher level of authority, better facilities, improved status, and usually a higher pay. This is a vertical movement upward in the organizational hierarchy. Promotions strongly motivate employees by rewarding past performance and encouraging them to work harder toward greater achievement.
Step 4: Compare both methods.
While transfers offer flexibility and multiskilling without a change in grade, promotions offer a direct incentive that boosts employee morale and loyalty to the company. Both methods save the time and cost associated with external recruitment.
Step 5: Mention the advantage common to both.
Both are economical and reliable because the organization already has firsthand knowledge of the capabilities and work history of these employees, reducing the risk of a poor hiring decision.
Step 6: Conclude.
Transfers (horizontal movement across roles or departments) and Promotions (vertical upward movement with higher pay and responsibility) are the two main internal sources of recruitment.
