Basically what this bill proposes to do is to return the sick leave regime to the negotiations process. The impact of the costs of sick leave.... Currently the collective agreements contain provisions around sick leave; therefore, there's an allotted number of sick leave days and there's a disability regime that is in place. What Bill C-4 proposed to do was to remove that and impose a sick leave regime that would impose upon the public service the new regime and disability plan, as well.
