I agree with you but I wonder if a court might say it's more like hiring a gardener to water your flowers and then when he doesn't want to change your flat tyre

I agree with you but I wonder if a court might say it's more like hiring a gardener to water your flowers and then when he doesn't want to change your flat tyre you cancel the contract. At the end of the day though short term/casual contracts are cancellable. I don't think anyone wants a world where you can't get rid of contractors when you want or need to.
