During negotiations for a collective agreement, a large number of employees were absent from work due to alleged illness just prior to a potential strike.
The employer denied sick leave pay to many of these employees, suspecting an illegal strike or 'blue flu'.
The union grieved the denial of sick leave.
The Grievance Settlement Board held that the onus was on the employees to establish the legitimacy of their illness.
Given the mass absenteeism and the inadequacy of many medical certificates provided, the Board found that the majority of employees failed to discharge this onus and were not entitled to sick leave pay.
However, employees who provided adequate medical certificates or who received express assurances from management that a certificate would ensure payment were found entitled to sick leave.
