Article 4(2).
Following the coming into operation of the Trade Union Subscription Deductions (Northern Ireland) Order 1999 you no longer need to re-authorise payments of trade union subscriptions by “check off” (deduction from wages by your employer) every three years and your employer need not give you advance written notice of any increase in the rate of deductions. The law continues to require your written authorisation before check off can start, and you continue to have the right to stop paying by check off at any time, by giving notice in writing to your employer.
This notice affects you if you pay your union subscriptions by check off and you gave your current authorisation before the date on which the Order came into operation.
If you are content for the new arrangements to apply for you, you need do nothing.
If, however, you wish the previous arrangements to continue to apply to you, you must give notice to that effect in writing to your employer at [name and address of employer] within 14 days of receiving this notice.
If you do so, your current authorisation will expire three years after you gave it, but any subsequent authorisation will be subject to the new arrangements.
