Final answer:
Commanding officers can approve up to 12 weeks (90 days) of non-chargeable adoption leave (TYPE T) for employees needing time for family reasons such as adoption.
Step-by-step explanation:
Adoption leave, categorized as TYPE T (non-chargeable leave), grants commanding officers (COs) the authority to approve up to 12 weeks of unpaid leave per year. This protection is provided to employees for family-related reasons, which include the need to care for a newly adopted child or a family illness. The equivalent period for this duration is approximately up to 90 days, aligned with the standards of employee rights for family care.
