It's really none of the employer's business how or why someone is sick. If they're legitimately booked off work and within the parameters specified by labour law then the company has no recourse. Do they really want the labour department going over their company policies with a fine-toothed comb, because if their sick policy is anything to go by they're probably breaking the law elsewhere too.
It's totally unreasonable and it sounds like someone needs to bring down the labour hammer on them. There's absolutely no reason any employee should use their annual leave unless they've run out of sick leave.
Ummmm.... wrong. I was about to post what DJ... posted regarding the allocation of sick leave in the first 6 months of employment. It would appear that the company was gently reminding her of her sick leave days still available to her. They have not started any incapacity-type proceddings...
