My partner is an electrician and has been working non stop throughout. But this is England, and the company he works for does most of its contracts for the local council. So he has been doing lots of testing and other apparent 'emergency' work. He is alot quieter than usual though, quite often he is working local now so he will do a job in the morning, come home for an hour or 2, then back out to work, and so forth. Thats opposed to before lockdown where he would be out of the house for the full day. Im unsure of the rules, laws, but i assumed its only emergency work that is allowed to be done.
