how does hiring a various and divers workforce affects the employee retention

I need 2 pages of literature review about how hiring various and diverse workforce in an organization can retain its employees.
for example:
1- hiring the right person in the right place can retain the employee in the organization.
2- having a diverse workforce with different skills can retain the employees.
3- having enough employees in the team to do the job and not to eliminate some positions to save cost, such actions will create stress and work overload.
