DP works full time, I'm a full time carer for my son so can't work. He's done his back in and needs to take a few weeks to a month off sick. SSP is only £94 a week. Would we still have to pay full rent and council tax out of that? Because that would leave us with less than zero. He's tried to carry on working (manual job lifting heavy steel and welding things) but his back is getting worse and just needs to rest it for a bit. TIA
