Police and PSOs will resume industrial action in Victoria next week after failing to resolve a pay dispute with the Victorian government.

The action will include alerting motorists to speed cameras, writing EBA slogans on police vehicles and putting up posters at police stations.

The Police Police Association (TPAV) is seeking a six per cent annual pay rise over the next four years and an end to unpaid work at the beginning and end of shifts.

TPAV secretary Wayne Gatt said negotiations with Victoria Police had broken down.

"Our members have seen other workers receiving higher pay rises and they feel that the nature and importance of their work to the community, should be held in the same regard and attract the same rewards," he said.

Victoria Police would not comment on the pay discussions.

A spokesperson for the Victorian government said negotiations were ongoing between the parties.

"Victoria Police officers play a critical role in protecting the community and saving lives, and we thank them for their vital service to the state," the spokesperson said.

"All parties continue to engage in good faith to negotiate a new enterprise agreement.

"Any planned protected industrial action is a matter for The Police Association of Victoria, and we welcome the union's assurance that community safety will not be put at risk during any industrial action."

Next week's latest industrial action continues a long-running pay dispute between TPAV and Victoria Police that saw members take action in December last year.

An agreement appeared to have been reached in May that would have seen Victoria Police gradually introduce nine-hour shifts and nine-day fortnights by 2029.

The deal also included a 16 per cent pay rise over four years which TPAV described at the time as "good for Victoria Police, our members and the community".

But the deal was ultimately rejected by union members, sending the parties back to the negotiating table.
