Teachers are in school whether or not schools are fully open like they are at the moment or only open for vulnerable and key workers. Teaching unions are paid to protect their members, and at the moment, schools are a hot bed of transmission more than anywhere else.
Rather than blaming the profession and implying that members are lazy, blame the government who promised to provide vulnerable children laptops so they can access learning at home but haven’t. If this was done as it was supposed to be the first time round, we would be in a position where learning at home and accessing school part time could be a workable solution. Instead, the government is happy to blindly allow the key demographic of transmission to continue to spread this virus for nothing but political reasons.
