Contract

All members of Torchwood One signed a contract which bound them to continue with Torchwood right up until their deaths, barring a dismissal from Yvonne Hartman. This meant Tommy Pierce was not allowed to retire, (AUDIO: Retirement Plan) and Guleraana Arbid would not be permitted to leave and seek other employment. (AUDIO: Uprising)

Unlike both operatives and office workers, outsider personnel under contract at Torchwood Tower — janitors, bin emptiers, window cleaners, and those in printer services, all of whom were regularly retconned — were provided pensions and permitted to retire.

However, Ianto Jones questioned whether Torchwood One outsider personnel, like Dave Cooke the cleaner, had had the support staff retcon protocols mentioned in their employment contracts. He argued that Dave had not willingly agreed signed off his memories for 10% above minimum wage and 4 weeks off a year for holiday. (AUDIO: Locker 15)

The assassins of the Lesser Order of Oberon, of which Doom was a member, used contracts for kills. If an individual was contracted to die, the assassins would make sure they were killed. (GAME: Lost in Time)
