@L777 I work connected to the construction industry. My experience is that theres lots of H&S guidlines and it is being adhered to. Its taking an average of 20% longer to get our guys on site at the moment, because of H&S. Which is good and that is strict on site.
Companies are terrified of being reported to the whisleblower line and being closed.
Obviously that's not everywhere.
As a manager, people will moan to him. Thays his job. He needs to ensure they remain 2 meters away. Thats for him to manage.
And someone has the job, on site of making sure the construction workers are adhering to the new guidence.
My mum is shielding and dad works in the NHS. So it is manageable in the home, but theres a lot they can do on site to limit his risk.
Would he have to leave his job or are they offering him unpaid leave? Obviously what you choose to do
Your risk once you have given birth decreases. Then will decrease as you recover from the birth.
Him going to work, after the birth would be slightly less of a risk, to you, than him going now.
