Having just read this piece, and combined with when speaking to agents about gigs and always asking for feedback on CV trends and my specific content, the sequential and standard approach to CVs has tended to be what they require.... For better or worse.
Not that for a moment I would think their (the article author's) CV style would sway anyone in an IR35 debate. Even if you include two or three other current contracts on the CV to demonstrate not being dependent on the one source of income, this would still have to be proved with contracts and a Q&A with your clients. And so to my mind, should just be left off the CV in case they think you don't have any time left for them...
Anyway, going back to Perm. Not a chance.
