The current enterprise agreement does not force drivers to work weekends, and if they choose to they are not paid weekend penalty rates.

Thousands of weekend services have been cancelled since the government launched its extended weekend services in late April.

The government's action plan to improve weekend bus service reliability was tabled in the ACT Parliament on Tuesday.

A key part of the plan is temporarily cutting the frequency of local weekend services until it can staff the routes.

The new timetable will be released later this week and come into effect on September 28 but the government said all rapid routes would remain.

The plan said the government would consult with staff and unions to identify potential changes to conditions that may improve weekend reliability.

These include weekend rostering and incentives for drivers working on weekends.

The plan said it would prioritise recruiting drivers that were interested in weekend work.

Transport Minister Chris Steel said 250 bus driver job applications had been received since mid-July.

"I am confident these range of short-term, medium-term and longer-term actions will deliver an improved weekend bus service while also providing a range of improvements which will benefit future weekday bus services as well," he said.

Greens transport spokeswoman Caroline Le Couteur said the government must commit to restoring full weekend services as soon as possible.

She said she was concerned the issues would remain until the enterprise agreement issues were resolved.

"Long-running problems like the lack of weekend penalty rates must be fixed," she said.

"This requires all parties, including the Transport Workers Union, to come to the table on this all too important issue for Canberra public transport users."
