I've never understood rhis whole "no sick leave" there (we get 10 days a year minimum and it accumulates).
Not only is it counterintuitive (sick workers spread illness), but given the somewhat litiginous nature in the US, I would think it would leave a business open to a lawsuit.
I mean if someone got sick who visited a place of business where a sick worker was effextiveky made to work, well damn tbey are well right to be pissed off.
