The workforce is the labor pool in employment. It is generally used to describe those working for a single company or industry, but can also apply to a geographic region like a city, state, country, etc. The term generally excludes the employers or management, and can imply those involved in manual labour. It may also mean all those that are available for work. Workers may be unionised, whereby the union conducts negotiations regarding pay and conditions of employment. In the event of industrial unrest, unions provide a co-ordinating role in organising ballots of the workforce, and strike action.
