Retaining key employees is an important consideration for a company to be successful. Retaining these key employees also retains all of the knowledge that person has from working on past company projects which is a useful asset that a new hire can’t offer. Retention of resources is also important because they have already been trained for the job and have a degree of experience in the job where as a new hire will likely need some level of training for the job and doesn’t have any experience working for that particular company.
