There are strict protocols for dealing with redundancy , including proper consultation, none of which Tom followed.
But so far as Tom was concerned Jazzer wasn't being made redundant?
YY to the way TV and radio ignore the reality of employment and housing law because tedious things like working out notice and going through proper eviction or redundancy or recruitment procedures aren't sufficiently dramatic for them. Hence we get people turning up in MN and elsewhere firmly believing that they have to leave their house immediately because their landlord has served an eviction notice; and it's a running joke on the Casualty discussion thread that virtually no-one ever gives in their notice before leaving a job, they just decide during the course of an episode that they're off and at the end they're walking into the sunset. Likewise, they never go through a boring process of advertising vacancies, drawing up job descriptions, interviewing, taking references etc - someone who someone knows turns up one day, the next day they're on the permanent staff.
And don't get me started on the legal farrago that was the second series of Broadchurch ...
