I am due a backdated consolidated LU pay award, how will this affect my contributions to the Fund?

Your contributions for the calendar year are assessed in November of the previous year and are effective at the new rate from January, the only exception is if you change your working hours in which case your contributions are reassessed at the effective date of your change of hours if that falls after November of the previous year.  Any arrears of contributions due will be automatically collected by payroll when you are paid arrears of salary.
