Absolutely, but personally I think there is logic in this. You can't get to 80% without first getting to 50% then 60%, and as we have seen already on this forum some see 80% as not doable. 50/60% by the end of the month are definitely doable and will see some benefit if as suggested the priority is in highly vulnerable workers.Saying '50, 60, 70%' is her new thing.
When pressed on accepting rising hospitalisations and deaths she suddenly changed to '70, 80%'.
I think 50% is a carrot for which there will be very little reward.
Today she was very clear that clearly 50% doesn't offer the same benefit as 80% but if 80% is regarded as a hard ask then using the promise of opening up is a strong incentive to at least get us well on that journey.
