Are you talking pay related as last paragraph changed
Part-time employees on the payroll as of 7/31/13 7/31/18 who are subsequently promoted to full-time employment will be paid their current wage rate until such time as the calculated progression rate exceeds that rate. The transfer date will become his/her full-time start date for purposes of applying the above progression.
Or
Layoff procedure, which is actually the last paragraph in Art 53
One (1) day (by the end of the previous work day) unwritten notice is required for layoff of less than fourteen (14) days. The Company is obligated to give as much notice as possible. Except for employees who do not have a telephone, the Company is obligated where possible and as soon as possible, to attempt to notify employees when an emergency occurs beyond its control. Notice must be given before the employee’s regular starting time. The Company shall be deemed to have fulfilled its obligation when an employee is called and does not answer the telephone. In the event of an emergency, available work shall be performed in seniority order by employees normally assigned to that work and that starting time within the classification.
