From what I have been reading here this double deduction is not an isolated incident. It looks as though it may be a more widespread problem. Be sure to check your pay stub for this week to see if your dues were deducted again. I checked mine tonight and I was double dipped too. Called my steward and he told me that it was a UPS payroll error, not a Union mistake. You are protected against such shortages under article 17. which includes the following language: Wages for properly selected vacations, in all instances, will be paid to the employees no later than the workday prior to their vacation. If the employee does not receive his/her vacation check, the Employer will make all reasonable efforts to provide the check the following day including delivery by Saturday or Next Day Air. Other shortages involving more than thirty dollars ($30.00) for full-time employees, and fifteen dollars ($15.00) for part-time employees, will be corrected and the payment will be made available to the employee at his/her reporting location on his/her second scheduled workday after. If the Employer fails to make the payment available on the employee’s second scheduled workday and the shortage was the result of the Employer’s error, the employee will be paid an additional amount equal to one-half (1/2) of his/her daily guarantee at his/her regular hourly rate for every full pay period in which the shortage is not paid after the second (2nd) scheduled work day, until corrected. Be sure to notify your supervisor at start time if you have been shorted on this weeks paycheck.
