The other problem is is who is going to police it? He hasn’t managed and policed the social distancing so why would this be any different.
Potentially mask wearing is easier to police, you are or you are not, there is no judgement or measuring tape required, you don’t need to work out who moved into the other’s space etc.
Please don’t think for one minute I’m against it as that isn’t the case. I just want to make sure it’s done properly if we do it.
I don’t think it will be long before it’s mandated as per Scotland (and Wales?), but regardless of that – if (a) it reduces the risk of Covid and/or (b) it reduces the risk of being told to self isolate because someone in the same work area was positive – it seems like a no-brainer for both staff and management. The union’s only legitimate concern (assuming it doesn’t stop people doing their job safely/effectively) could be how you will deal with rule breakers.
