A note explaining the UK government's Job Support Scheme (JSS), which was originally due to apply from 1 November 2020 to 30 April 2021. The scheme was designed to provide two separate levels of support: first, to employers facing lower demand over the winter months due to the COVID-19 pandemic and second, to those employers that were legally required to close their premises as a direct result of local or national COVID-19 restrictions. The note explains in respect of each part of the scheme: who was covered, how an employer was to implement the scheme, and what the employer could claim back.
