Tea break over, it's back to work. Tony Robinson's nose gets firmly back to the historical grindstone in a second series of The Worst Jobs in History.British history has only happened because of a lot of people doing a lot of terrible jobs. Tony looks at some of the horrendous tasks behind some of the most important strands of British history.In five episodes he sees how the events, institutions, emblems and economics that have made us what we are have been brought about by an anonymous army of workers.Episodes cover Britain's Urban, Royal, Industrial, Maritime and Rural history. In each programme he tries his hand at a number of jobs and then decides which is the very worst of all - before doing it for real.
