Final answer:
The option that is not a common reason for instituting a flex work arrangement is to increase performance review scores as the primary goals are to attract talent, save costs, and improve attendance.
Step-by-step explanation:
You are asking which of the following is not a reason a company might institute a flex work arrangement: To improve recruitment, to save costs, to increase performance review scores, or to improve attendance. The option that is not a common reason for flex work arrangements is C. to increase performance review scores. While performance reviews may improve incidentally due to increased morale and productivity resulting from flex work arrangements, the primary purpose of these setups is not directly tied to performance review metrics.
Flex work arrangements often aim to improve recruitment by attracting talent who value flexibility, save costs on office space and resources, and improve attendance by allowing employees to work during hours that suit their circumstances best. These benefits can indirectly lead to better performance reviews but are not the direct goal.
