The advantages of internal sources of recruitment are:
(i) Employees are motivated to improve their performance as a promotion at a higher level may lead to a chain of promotion at lower levels in the organisation.
(ii) Internal recruitment also simplifies the process of selection and placement as the candidates are already known to the organisation.
(iii) People recruited from within the organisation do not need induction training.
(iv) Transfer has the benefit of shifting the workforce from the surplus departments to those where there is a shortage of staff.
