Charles Sturt University (CSU) confirmed it would not agree to provide for additional paid leave for staff experiencing domestic violence as part of current enterprise agreement negotiations.

PSA urged CSU to "acknowledge its responsibility" and accept an enterprise agreement which sensitively and fairly delivered support for victims of domestic violence.

"The impacts of domestic violence on victims and their families can be brutal and far-reaching," PSA senior industrial officer Andrew Holland said.

"CSU should be a model employer in its support for employees facing domestic violence, rather than resisting support measures.

"Having dedicated, paid leave for staff experiencing domestic violence, or taking action to stop abuse, gives victims a better chance of addressing their circumstances without additional stigma or discomfort."

CSU workplace relations and policy director Mal Wilson said the university was supportive of employees facing domestic violence.

"The university views any such incident as a priority matter to be handled with sensitivity," he said.

"CSU has offered paid leave to cover situations of domestic violence requiring time off work and sought to include this under 'personal leave' rather than create a separate section in the agreement for domestic violence."

He said this approach would better allow any such matters to be dealt with confidentially on an individual basis.

"CSU has a range of workplace support initiatives in place for victims of domestic violence and will continue to treat the issue as critical to the ongoing well-being of all staff," he said.

Leave to support staff experiencing domestic violence has been a key condition requested by university employees.

The new clause is now being included in many public and private sector workplace agreements.
