I run a small business, with my wife and I as salaried directors. We are nowhere near "key workers" so my wife's side of the business needed to be put on hold when we went into isolation just over a week ago and she needed to look after both our children full-time. Luckily, she should be covered by the UK's wage relief scheme, so 80% of her salary will be repaid by the government from the end of April.
My side of the business looked a bit dicey a week ago, but I've recently had new contracts signed that should secure my income until autumn, although I am working nights a lot at the moment to keep on top of everything while my wife home-schools and looks after the kids. I realise I'm lucky to be in the position I'm in, though, so I'm not going to complain about working a bunch of late nights to keep our income flowing; there are people out there doing far worse for far less.
