sorry to say but you are NOT covered by workcover or company insurance when you are travelling to and from work. The relevant legislation was changed 2 years ago to say that you are only covered whilst on official work duties, any travel to or from home or even lunch breaks are no longer covered. Also, if you have used your entitlement of sick leave, all that remains for you is to take leave without pay. They cannot fire you for being injured and unable to complete your duties, however if they do, depending on the size of the organisation you may be able to sue for unfair dismissal. Your best bet, as horrific as this sounds, is to go see one of those no win no fee accident lawyers, and see what case you have against the person who hit you. Sorry mate.
