Do I have to serve my notice period in my contract?

You can use MOO if the project for which you've been contracted gets cancelled before the end of contract. When it occurred to me, the client just expected to assign me to something different. I invoked lack of MOO and walked after a face-to-face meeting with the client the following day.

You can't walk just because you don't like the work.

I've never been entirely convinced by this argument around MOO.

Most things I've read indicate it is more to do with the end of a contract and whether they client/contractor is obliged to offer/accept a contract extension.

When I've discussed this with someone from Accountax in the past, I've been told if the client has the unilateral right to terminate the contract immediately due to e.g. unsatisfactory work, it could be said that there is no MOO as it only flows in one direction, with regard to MOO during the contract. They take a cautious view when doing a contract review and would fail it on the MOO aspect, if you can't evidence there is no MOO during the actual contract, but as mentioned, the aforementioned factor would point to a lack of MOO during the contract due to its unilateral character, as would of course a lack of obligation to accept any further work the agency or client are willing to offer upon its termination (natural or otherwise), i.e. what Cojak mentioned.

and that is quite different from the post I quoted which mentioned no caveats, just "you can just leave whenever you like because of this"

And there was a good reason why I prefixed that post with "There are many arguments around MOO" as I knew a lively debate would quickly follow!
