if he is self employed contractor why is he working 6/14 and just won't rather take less hours to have better balance and more energy?

it seem they were doing fine before, sure no savings, living in rent, but it's still better than destroying your family and killing yourself for few extra quid, isn't?

also if he doesn't like this delivery company why not just find different? it's not like there is only one in market, not sure about situation in UK, but here in Czechia all companies would be kissing his ass to work for them with zero unemployment

it also strikes me a bit odd they are delivering 6 days a week, why are they not having weekends for delivery companies? how is it even legal to work 6*14=84 hours a week contentiously, that's more than 336 hours per month, pretty much double of normal workers
