So... I had to stay at home because DS2, almost a year old, had some strange nappies on Tuesday and nursery asked us to observe the 48 hour rule. My husband covered Wednesday, I covered today. Really annoying timing as I am preparing for the new semester and am behind as it is. Plus, I don't have a properly sick child that sleeps a lot... oh no, I have a baby who is just learning to stand, can't be left alone for a second and didn't think much of the idea of sleep.
In this case, I didn't say "officially" that I would be at home looking after a sick child - I just cancelled a meeting with PHD student (he would be meeting the co-supervisor by himself) and that's it.
The precedent to this is that, a year ago, DS1 had chickenpox. I made the mistake of e-mailing the administrator that I'd be working from home for the next few days and that I wouldn't be there for certain meetings. This was at the end of May, so no teaching, just lots of marking. The e-mail was a mistake in the sense that I got a snotty reply from my line manager that she couldn't approve me working from home whilst looking after dependants, and that I would have to take one day as annual leave (the other three were put down as carer's leave). I felt a bit annoyed at the time as, if I hadn't done my marking from home (I used nap times and evenings), nobody would have done it for me and the deadline was close. But never mind!
So how do you deal with this? Say nothing and just 'work from home' (unless you have teaching)? How do your institutions deal with this? I actually think that my current line manager, who has kids himself, will be much more flexible with all this.
