I used to work security and i was aware that for that line of work anyone that was working nightshift was required by law to be double manned, i believe. Is this a requirement for all jobs that work antisocial hours? specifically for people that normally operate on their own during the day. Im a lorry driver but i deliver chicken feed to farms out in the sticks, the only concern would be that if anything happened to me on nightshift, injury etc, that i wouldnt be found until the farmer came to check the chickens in the morning. anyone in the know?
