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", at which point they were incinerated. (AUDIO: Zero Hour)
