I don’t mean in terms of supposed future lost wages because a child stayed home with a vomiting bug or something, I mean because e.g. child or teacher attended when clearly contagious impacting other staff, children and parents/siblings. I wonder how much it costs in parental time off, in susceptibility to additional viruses, in encouraging a mindset that contributes to the mounting costs of presenteeism instead of productivity. I’m also talking about less quantifiable costs e.g. not seeing grandparents, studying whilst feeling lousy, the awful rise of children with long covid, the messed up holidays, asthma exacerbations, glue ear, impact on nhs.
