A police officer may take time off because of:
Leave taken as time off for dependants shall be treated as duty, but does not apply unless the member tells their chief officer the reason for their absence as soon as reasonably practicable. Best practice would be to inform a line supervisor of your circumstances ASAP after you become aware of it.
A “dependant” means, in relation to a member of a police force:
a) a spouse, b) a child, c) a parent, d) a person who lives in the same household as the member, otherwise than by reason of being his employee, tenant, lodger or boarder.
This also covers when a dependant falls ill, gives birth or is injured or assaulted or in consequence of the death of a dependant.
