The group/phrase “shielding” ceased to exist on August 1st. They did their bit for 15 weeks, then were, as you put it “thrown under the bus”.
Which again no one agrees with.
If everyone not at risk was out working and going about the normal business from day one with tweaks there would be money left to shield for longer.
The monies gone, wasted on having people that didn’t need to be sitting at home.
