Sorry, but I absolutely despise this opinion.
I work in engineering / construction and the rate of deaths has sharply dropped since health and safety has been taken seriously.
Absolutely. The local authorities have a
statutory duty to keep these routes open. That duty has not been repealed, and the C-19 legislation is not higher law so does not usurp that duty.
It is clearly stated that if people cannot reasonably work from home they should go to work (unless they work in one of the business on the prescribed list) and work as normal, albeit maintaining distancing where possible and being mindful of hygiene.
There is nothing in the legislation that prohibits people other than "key staff" going to work. Indeed, I would contend that as they have a statutory legal duty to act, and failure to observe that duty is unlawful, they are indeed key personnel anyway. To wilfully neglect a statutory duty is misconduct ina public office, a serious offence, and being worried about C-19 is a mitigation, not a defence.
There is nothing in the legislation or any moral imperative that prevents councils from discharging their lawful obligations, and most other local authorities - including my own local one - are dealing with such matters, and actually doing so quite expeditiously.
Interestingly, most of the highways stuff is managed by contractors, in my local council Kier. Its utterly obscene that some council contractors are still taking the full public coin yet using this as an excuse to not even attempt to provide the contracted services.
