This reminds me of another question I have, but is close enough to this topic I'll just ask it here.

What are your people's standards for calling in sick legitimately? Do these standards vary depending on the job/work?

For me I skip class if it's anything like the flu or worse where moving makes it worse, so if I went to class I'd feel like shit and barely pay attention, but if I sat still I'd recover by the next morning.

If it's placement or work (which for me so far in life has always been around children) I call in sick if it's anything I am worried about being contagious. My concern being the children's health are my priority and I am doing them no favors coming in spreading a sickness to all of them, even if I can still technically work fine without it (common colds don't count here, that would keep me home for a full week and colds are common place in everyone regardless). Children are generally weaker to diseases than adults and I don't need to be coming in giving them a sickness that by most probability will be worse for them than it is for me.
