The union acts as a collective organization to serve its registered members in private and public prisons. This includes addressing government procedures and providing media coverage of issues relating to prison cases and controversy or related to them.  The union expressed concerns about the lack of access to mental health for prison officers compared to other front-hand workers such as police officers.  Those eligible for union membership are employees of a prison or prison in Western Australia. A member`s membership is revoked if he or she leaves his position in the prison service. In the event of the departure of a person wishing to terminate his membership, a written resignation with a period of 14 days is required.  Individuals are still responsible for all subscriptions or taxes that result in up to the included withdrawal date.  WAPOU Secretary Andy Smith called for public opinion and the government to better understand the traumatic and disturbing circumstances faced by prison officers on duty, the fighting, riots and injuries of prisoners.  In 2018, Smith reflected on the 12 VA officers who have committed suicide in the past 14 years.  The union argues that understaffing and overcrowding only increase labour pressure.  The union took over the allocation of funds for employment in the private sector. A 2015 report indicated that 53% of public system funding is for the employment of public servants.  The report proposed that private systems spend 3% of financial resources on the employment of their employees.
This assertion was refuted by independent audits conducted by the private system in the VA, which stated that this claim could not be made because the resources of private facilities are not made public.  In 1981, the government introduced the Prisons Act, which highlighted the state`s expectations of the role and responsibility of the prison officer. Prison officers were expected to be faithful to the new act. The WAPOU has publicly opposed the introduction of this new law;  On November 16, 1981, in The West Australian newspaper, the union filed an article stating that the law did not respect fundamental civil rights.  The result of WAPOU`s public action resulted in a change in the original act. The act was amended so that only newly recruited officers would be required to take an oath of allegiance.  Successful graduates continue to learn in the workplace and are qualified nationally, CSC30115 Certificate III in Correctional Practice (Custodial). After 9 months of probation, officers may be recommended for tenure until satisfactory performance and achievable conclusion. In 1992, officers from Fremantle Prison established the Retired Prison Officers Association to recognize a very unique group of collaborators. As a prison officer, you are in a stressful and dangerous environment like no one else.
After retirement, a public servant leaves the workplace, but unlike any other job, he or she cannot at any time return to or talk to a former co-worker. The RPOA was created to find out and works through a group of volunteers to organize social functions throughout the year, where retired officers can gather for lunch, dinner or drinks with other retired officers from across Western Australia.
