Re: Will be delayed (again)
MOO is indeed complex but I believe that being obliged to offer and accept work at the end of a package of work is not MOO.
There have been arguments in court that there can be MOO within a contract.
I believe that to demonstrate a complete absence of MOO the engager should have a right to not offer any work and the contractor should have a right not to accept any work.
Some agents will not accept an explicit absence of MOO because it doesn't suit their purposes of a constant and guaranteed income stream. For engagers/clients it gives them freedom to end or suspend the contract at any time.
