I am an extremely conscientious person and have followed all of the guidelines to the letter. I also take huge care not to pass Covid on to my vulnerable friends and relatives - I've stopped seeing my elderly parents until we can isolate for 5-8 days beforehand (5 seems reasonable now as Omicron has a shorter infection gap) and I do LFTs too.
BUT I will simply have to follow these guidelines and send my child in to school when they are feeling up to it, EVEN if I know in my heart that they are likely to be infectious.
I feel awful about it in advance, but as a single working parent there will simply be no slack cut for me if I try to take more time off work than is outlined in the guidance. I cannot keep sacrificing myself at the expense of my family, if the government have an ounce of common sense they would never be putting ordinary working people in this position.
Also please note that absences beyond that timeframe are highly likely to be unauthorised and fines issued for non-attendance at school!
This is a systemic problem. Personal responsibility is not enough to solve the societal lack of caring here.
