Zero-hour contract
From Tardis Wiki, the free Doctor Who reference
A new Welsh law established around 2018 dictated that a person could only be on a zero-hour contract for twelve weeks before being entitled to basic workers' rights.
Deliverables exclusively offered zero-hour contracts. To get around giving its employees sick pay and holidays, it burnt its employees just before they exceeded the twelve-week period, or earlier for seniors and employees with disabilities. Employees about to be permanently retired were called into HR for their "benefits package". (AUDIO: Zero Hour)
