Leaving a job voluntarily

peachy123

hi. Thank you for reading

I am married husband works full time…I currently work full time. I have fybromayalgia,osteoarthritis,anxiety and depression. My fybro has been so bad lately. I feel I can’t carry on working full time. If I gave up my job voluntarily because of my health or possibly cut my hours to say 10 a week could I claim benefit right away or be sanctioned. Would I have to surrender sick notes for a certain amount of time? I so can’t face the whole journey with my employer for them to let me go through ill health 😔 I couldn’t cope with the harassment to either give up or go back!
I receive ADP lower living. No mobility
