Public servants get 15 days of sick leave a year, which they can accumulate and carry over year to year. Sick employees must exhaust their accumulated sick leave before they qualify for disability, which covers 70 per cent of salary. The plan has a 13-week waiting period so anyone with less that 13 weeks of accumulated sick leave is off work without pay other than employment insurance sick benefits.

It’s expected the government will want a sick leave model similar to the one at Canada Post, which became a strike issue when introduced. Canada Post employees get seven days of personal leave, and once those are exhausted they have to go on short-term disability and are entitled to 70 per cent of salary. They cannot accumulate or roll over more than five unused days.
