Point of clarification,before an important subject loses it's way,the retirement age in NATS is 60,operational ATCO's with 29 years membership of the Pension scheme AND a minimum of 20 years service with validations( with some other qualifying restrictions),can retire at 59 without loss of abatement,a reduced abatement of pension based on the'standard' is available until age 54,in addition ATCO's subject to management agreement can continue employment until 65.We do NOT have to retire at 55,though many wish!!!
