No, I don't. Now, I don't take a lot of sick days but I DO take days off for personal reasons - holidays, just want a day off etc. And I never feel guilty.
How many parents do you have in care who routinely take a day off work and STILL bring their child to care?? My guess is that there isn't a single provider on this board who doesn't have at least two or three of these parents in their care.
My point is, if the parents can take a PAID day off work, dump their child in care, and then go back to bed then why should we feel guilty taking a day off too??
