Please talk me down. I am so pissed off right now.
DH (aged 52,) works in a petrol station. 27 hours a week. (Three 9 hour shifts.) He used to do 36 hours but dropped his hours last year to 27, as he was 'finding so many hours tough.' He works behind the counter (and behind a big pane of glass,) and he is alone about half the time.
Now, with this pandemic going on, he is driving me nuts. For the last 2 weeks, (and non-stop, for the last 5-6 days,) he has been saying 'I am probably gonna self-isolate soon, as I am 52 and in the 'at risk' group.' And 'our place needs to shut down soon, or 'I'm just gonna call in sick.'
For context, as much as I love him, he is a shirker when it comes to work. He will do stuff around the house and garden if you push a stick of dynamite up his arse, but won't volunteer, and happily sits watching TV every waking hour that he is not at work.
I seriously think I'm gonna knock him out if he doesn't stop threatening to 'self isolate' and/or go on the sick.
He has NO underlying health issues, he has NO coronavirus symptoms, and he only has to do three 9-hour shifts (isolated from the public pretty well,) and then he has 4 days off.
I have tried to explain that he CAN'T just 'self isolate' with no symptoms at all, and no 'go-ahead' from any medical professional. And he can't just 'ring in sick' or not go to work 'because I think my place should close...' as he will NOT GET PAID.
As if life is not stressful enough with this pandemic and all the worries that go with it! I am getting so stressed and pissed off with my idle, workshy husband trying anything and everything to get out of going to work! 
Sorry, I just needed to vent. What can I do? (If anything?)
