Between Jobs.

From the Herald Diary, "POLITICAL candidates will look for any favourable signs that they are going to do well in an election. We bump into Peter Grant, the local council leader who is the SNP's candidate in the Glenrothes by-election who tells us excitedly: "I've just got a new tax code from HMRC with a letter saying We believe you are currently between jobs'.
"Do they know something I don't?"

Probably.
