Personal History is complete, with no gaps, and is accurate.
At the moment, my Work History has only the two jobs which contribute towards my score.
For the Work History portion, it doesn't specify that there should be no gaps (obviously, because its not unreasonable for people to go for periods with no work) and states something along the lines of giving a history of work so that they can use it to calculate the score. I originally read that to mean that you ONLY give details of the jobs that contribute to your score. But then today, I thought maybe I had read it incorrectly.
Both sections are factual, and accurate. I haven't lied in either section. I'm just trying to determine if I have misunderstood what should go in the Work History section, moreso, if they are likely to highlight that there are jobs on my Personal History which are not included in my Work History.
I also don't know if, in the situation where they did want to know about the 'missing' jobs, that they would reject the application, or would they simply request more documents?
EDIT: I can answer my own question... why give them any reason to doubt it. Include it, with the letter, like you say, and if they want to know more, or insist I get the documents, then so be it.
Easier to make a little bit of effort now than to end up being rejected over being lazy.
