Anybody in paid employment has a contract of employment which starts when the employer say "You're hired." It's not a written document - although parts of it must be in writing - and it contains all sorts of things by implication. It's also often a changing contract. Ultimately, the only way an employer can try to force anybody to do anything is to say it's part of their employment contract and they'll be disciplined if they break that contract as in "You're fired." Although the main conditions of a contract of employment cover what's done "in the firm's time" that's not exclusive.
That a good point, however, there is still a limit to what an employer can demand of an employee outside of working hours. Contracts should define the working hours and place of work, and outside of those, the employer has limited rights to define employees' time & activities as long as they turn up on-time and fit to work.
I would think that someone dismissed in such circumstances would have a strong case for unfair dismissal. Of course that may not be much help, if it means being some months without pay, possible legal costs, etc.

Almost always good advice.
