The UK Consortium on Aids and International Development has published the first voluntary sector guidelines on managing HIV and Aids in the workplace.
Working Positively stresses the importance of developing a comprehensive workplace policy, including staff education on prevention, treatment and care.
"As NGOs we have a special responsibility to ensure our own house is in order," said Simon Wright, chair of the consortium.
The guide recommends that policies should also be supported by guidelines for managers on how to handle staff relationships and the concerns of HIV-positive staff.
It includes examples of workplace strategies, testimonies of people living with HIV and Aids, and a list of useful websites and publications.
"Charities and NGOs often work in some of the highest HIV and Aids prevalence areas in the world and typically employ staff from local communities," said Wright. "Good workplace policies and programmes can help mitigate the impact of HIV and Aids on an organisation, while at the same time lessening the overall impact of the epidemic."
