We are currently in the middle of some building work. We are having an extension built (just about out of the ground now). I do not know if I need to tell the builders to down tools or not because of the shutdown. Some germane facts: 1) Two builders on site, and they are maintaining 2m distancing. 2) The build is to accommodate my disabled mother-in-law. Her condition is deteriorating. 3) It is very noisy and dusty, which is annoying to neighbours who have no choice but to be home. 4) The noisy / dusty bit is about to end as they are about to start on blockwork and brickwork above ground. 5) The builders are adamant that they want / need to keep working, as they do not like the look of the governments plan for 80% wage payments. They are especially concerned it doesn't kick in until June. 6) We are maintaining strict separation from them. 7) The government has not ordered the shutdown of building sites, so some are closed some are not. 8) The builders tell me that the majority of their friends in the trade are still working, albeit on smaller projects like mine. We feel a strong ethical need to do our part in stopping the virus. We also have a moral duty to my MiL and the builders. I do not feel that this one is at all clear. Opinions?
