Depends on a lot of factors really. PL referees tend to get temporarily "demoted" for significant errors, so will generally still referee in that time, just for Championship or L1/2 games. But I think a huge part of why that's done is because the PGMOL have an obligation to supply SG1 referees for a certain proportion of lower league games each season - by using it as a punishment, they kill two birds with one stone, while also not having to pay them the fixed salary to do nothing (3 birds?).It's also 3 weeks of not being able to enjoy what you do. To think of it as a holiday, is wrong IMO. Thinking about how after a couple of postponements I am chomping at the bit to get back.
I suppose she could. Still pick up local games???
But, at grassroots level, I think you could expect this kind of error to result in a full suspension from refereeing for that time. Without knowing more about how referees are arrange for top level women's matches, I don't know where on that scale this would fall.
