No idea if anyone will be able to help with this one, as a bit obscure, but...
Part 5 of the ESA1 form asks about current work you are doing now. It asks for the date when you last worked.
I work for my own 2-person company (i.e. I'm not self-employed but PAYE employee and also a Director).
I have been off sick since 27/1/14 and so I could put that date in.
However, prior to that I had been on unpaid absence of several months for two reasons: 1) as the company was struggling and we had no money to pay me, 2) my partner (in life and in the business) had become very ill herself and I was caring for her a lot of the time.
So I'm wondering should I put the date of the start of my unpaid absence in?
