I hereby request and voluntarily authorize my employer to deduct from my earnings and pay over to The Local the regular monthly dues uniformly applicable to members of The Local. This authorization will remain in effect and shall be irrevocable unless I revoke it by sending written notice to The Local during the period not less than 30 days and not more than 45 days before 1) the annual anniversary date of this agreement or 2) the date of termination of the applicable contract between the employer and The Local, whichever occurs sooner. This authorization shall be automatically renewed as an irrevocable check-off from year to year unless I revoke it in writing during the window period, irrespective of my membership in The Local. Union dues may not be deductible for federal income tax purposes; however, under limited circumstances dues may qualify as a business expense.
