The organisation I work in asked all staff to cancel Christmas parties/ gatherings 2 weeks ago due to the amount of staff having to isolate following outbreaks after staff gatherings.
It's a real shame, but if you have 40 or 50 people together with a virus as easily spread at this you can lose a workforce instantly.
I appreciate all the anti-lockdown rhetoric, but locking down/ stricter measures are often required to maintain a level of staff required to provide basic infrastructure.
A lot of kick back at schools locking down for example does not take into account that if 4 teachers have to isolate due to testing positive/ family testing positive then suddenly the school often doesn't have the capacity to open. If cases are high in the community infrastructure gets overwhelmed due to lack of staff to run as well as lack of people to care. Hospitals shut services because they prioritise keeping those acutely unwell alive, not because they prioritise a specific virus/ condition.
Some measures are simple, and if implemented well and sooner hopefully we wont have to consider more severe ones. If we pretend Covid doesnt exist it isn't going to disappear, and once we hit capacities in hospitals/ illness in key infrastructure then services will independently have to lockdown/ reduce anyway. E.g cancelling non urgent surgeries and cancer surgeries in hospital/ schools closing etc..
