Leave can’t be postponed (delayed) if:
the employer doesn’t have a ‘significant reason’, eg it would cause serious disruption to the business
it’s being taken by the father or partner immediately after the birth or adoption of a child
it means an employee would no longer qualify for parental leave, eg postponing it until after the child’s 18th birthday
If it’s postponed, the employer:
must write explaining why within 7 days of the original request
suggest a new start date - this must be within 6 months of the requested start date
can’t change the amount of leave being requested
