Short Term Disability Benefits

Short-term disability plans provide benefits to covered employees who cannot work due to disability caused by an illness or an accident that is not work-related. Benefits are paid for up to 26 weeks.

Benefit Trust Fund Short Term Disability plans pay 70% of an employee's gross weekly wages, up to a maximum weekly benefit amount that ranges from $200 to $1,000, as specified under each plan.

All Benefit Trust Fund Short Term Disability plans have a seven-day waiting period. A waiting period is the number of unpaid leave days that must elapse before benefit payments can begin. The waiting period starts when a covered disability, as certified by a physician, results in the first day of unpaid leave. The waiting period ends after seven consecutive unpaid days. Benefits begin on the first day of unpaid leave after the waiting period, while you remain totally disabled, provided you were eligible for Short Term Disability benefits on the date the waiting period began.
