Paragraph 6

At quarterly intervals, in order to take account of a change in an employee's earning capacity arising from any cause, the employer or the employee may give notice to the other of reassessment of the basic average wage. For the purpose of such reassessment there shall be calculated the employee's rate of average earnings for a 40 hour week exclusive of overtime, and all time lost by the employee on account of bad time keeping, during an agreed period of four full weeks of normal productive employment.

(NOTE: When a change takes place in the percentage additions to piecework rates in March and/or September, the pieceworker's basic weekly wage shall be adjusted by a percentage equal to the difference between the old and the new piecework percentage additions in force, with effect from the beginning of the working week in which the change takes place.)
