That does sound harsh but depends on what your operating procedures say. I’d have thought a verbal reminder appropriate if it was a first instance.
At ours we wear face coverings in all communal areas including labs, all offices are now single occupancy, no corridor chats, etc. Of course there are some exceptions like our big open plan sales area which is still multiple occupancy (maybe 1/4 desks used and big posted reminders to maintain SD) – not that sales are in, these are now overspill areas where lab staff offices are now single occupancy.
I’m totally impressed and on board with how our management and CV crisis team have kept on top of this, I feel very safe when in the office. Helps too that it’s a science business I think, far fewer CV deniers and a good understanding of the balance of risks versus individual freedoms, so adherence to policies is excellent.
