Should annual / long service leave requests lodged far in advance be given more weight / priority for approval in the public health system over other leave requests?

Long Service Leave and annual leave are given and taken at a mutually agreed time between employee and employer. There is nothing expressly written in the Public Health System Nurses & Midwives’ (State) Award or Leave Matters Policy Directive that states that leave requests lodged far in advance should be treated with more priority; the policy is silent on that issue. In general, managers are responsible for scheduling annual leave equitably throughout the year to manage leave liabilities and to prevent unreasonable increased workload for remaining employees arising from the taking of leave.
