One theory about employment recruitment focuses on comparing internal and external recruitment for a job position. Some benefits of internal recruitment are saving money and creating incentive within the workplace. The main benefit of external recruitment is a larger pool of candidates from which to select.
Internal recruitment occurs when companies select and promote employees who already work for them to new positions. This type of recruitment can save money because internal candidates require less training. They also have a smoother transition within the workforce because of their past experience at that company. Companies with a culture of internal recruitment also provide employees with an incentive to work hard because of the potential of promotion.
External recruitment enables employers to select from a larger pool of candidates, which can mean attracting the most qualified and talented individuals. Hiring from outside a company can also introduce new ideas and ways of operating to the workforce.
