The cost of health benefits for permanent employees is shared between the government and the employee. The government's share is approximately two-thirds (2/3) of the cost and the employee's share approximately one-third (1/3).
For permanent employees on a part-time work schedule, the government pro-rates the amount it will pay. The employee will be responsible for their share and the balance of the government's share.
