The union was formed in 1993 when three public sector trade unions, the National and Local Government Officers Association (NALGO), the National Union of Public Employees (NUPE) and the Confederation of Health Service Employees (COHSE) merged.
Members and organisation 
Members of UNISON are typically from industries within the public sector and generally cover both full-time and part-time support and administrative staff. The majority of people joining UNISON would be workers within areas such as local government, education, the National Health Service, probation services, police services, utilities (such as gas, electricity and water), and transport. These 'Service Groups' all have their own national and regional democratic structures within UNISON's constitution.
As a trade union, UNISON provides support to members on work related issues, including protection and representation at work, help with pay and conditions of service and legal advice. Each company or organisation will usually be represented by a particular UNISON branch and members within that organisation elect volunteer stewards to represent them. The stewards receive training in workplace issues and are then able to co-ordinate and represent members both on an individual basis and collectively.
Each branch is run by an annually elected committee of members which holds regular meetings, including an annual general meeting for all members to attend. Branches elect delegates to the union's annual National Delegate Conference (held in June every year), the supreme body within the union's constitution with responsibility for setting the union's policies for the forthcoming year.
To encourage all voices to be heard UNISON has "self organised groups" of black and minority ethnic members, women members, lesbian, gay, bisexual & transgender members, and disabled members. Young members and retired members also have their own sections within the union.
Membership fees 
The levels of subscription are determined by the National Delegate Conference and are recorded as a Schedule in the union rules. The National Delegate Conference has the power to vary the subscriptions levied after a majority vote, although the subscription rates do not change frequently.
Local branches may also, after a majority vote of members, impose an additional 'Local Levy' as long as the levy does not exceed one sixth of the subscription payable. This is in addition to the standard rate, and must be used for local branch purposes.
Membership fees vary depending on how frequently members are paid and the level of their current salary (see table). Subscriptions are generally paid by what is commonly known as "check-off" or DOCAS (Deduction of Contributions at Source). This is where the employer deducts the contribution from the employee's salary on behalf of the union. Payment is taken by Direct Debit if the member joins online, if the member specifically requests it, or if there is no DOCAS arrangement with the employer.
Student members in full-time education (including student nurses or Modern Apprentices) have a fixed rate subscription of £10 per year.
Members who have had continuous membership for at least two years may opt to pay a one-off fee of £15 upon retirement from paid employment. This allows them to retain the benefits of being a union member for life. They are then classed as 'Retired Members'.
Members who are dismissed or made redundant from employment may retain their membership for £4 per year for a period of up to two years whilst they remain unemployed.
Membership campaigns 
Various local campaigns are run by the union. Much of the recruitment within organisations takes place at a local level, with stewards and branches directly engaging with the staff within their remit.
The national organisation also engages in publicity  such as the "Ants and Bear", which was used at the formation of the new amalgamated union. This advertising campaign showed an ant trying to get past a large bear by shouting "Excuse Me", however the bear did not pay attention. The next scene showed the ant being joined by many thousands more, and them all saying "Get out of the way!" together, which does get the bear's attention and makes him move out of the way.
The General Political Fund funded a TV recruitment advert "You're one in a million" launched in October 2004.
Political work 
UNISON has a political fund which uses money from members for political and social campaigning. Members have the choice of paying into either a fund which supports the Labour Party, a non-affiliated General Political Fund or to opt out of contributing to a political fund at all. UNISON also carries out research and campaigns on public service issues, such as the Private Finance Initiative (PFI). It has also voted (at its 2005 annual conference) to oppose the Government's proposals for a British national identity card.
The union's links to Labour and its moderate policies has caused some conflict and criticism of action taken against left-wing activists.
In April 2009 a UNISON conference voted unanimously to request that the British Department of Health ban members of the British National Party from working as nurses in the National Health Service, describing the party as racist.
Political campaigns 
UNISON runs a range of national campaigns, such as 'Positively Public', the campaign to keep public services public and well-funded. Campaigns cover a broad area from pay and pensions to sector-specific initiatives focusing on a variety of issues from cleaner hospitals to opposing the sell-off of public housing.
The General Political Fund has also funded:
- Anti-racist events
- Local campaigns against privatisation/marketisation
- UNISON presence at various national and regional events
- Campaigns against council housing sell-off
In the run-up to general or local elections, the fund has been used for advertising campaigns to ensure that issues of importance to UNISON are high on the agenda. Its 2010 campaign is titled "Million Voices for Public Services".
The GPF is not affiliated to any political party, but the money in the fund is used to support local campaigns and to pay for political advertising.
