IR35, MoO and vacation

[SpontaneousOrder]

I'd say being project specific is the bare minimum to not imply MoO, but by itself not enough to show lack of MoO.

And presumably actually exercising it makes it rock solid.
I got the project name put into my schedule, although I'm not sure the client really understood the implications. I'm hoping that this project finishes in 3 or 4 months, rather than 1 or 2 (it's not 100% clear yet) so that I can demonstrate the lack of MoO by sodding off without any notice period - but without wasting the lion's share of a 6 month extension. I'd happily sacrifice 2 months of work for it though - especially as this place makes me want to kill myself.
