Employees have the right to return to their job if they take:
Paternity Leave
only 26 weeks of Maternity or Adoption Leave
only 26 weeks of Shared Parental Leave (between both parents)
4 weeks or less of unpaid Parental Leave
Parental Bereavement Leave
If employees take more leave
If the employee takes more leave they’ll have the right to their job or a similar job (if it’s not possible to give them their old job).
Similar means the job has the same or better terms and conditions. If the employee unreasonably refuses to take the similar job the employer can take this as their resignation.
