Trades union leaders have called for a campaign to increase the financial powers of the Scottish Parliament.
The union wants more financial powers for MSPs at Holyrood
Unison's Scottish Council discussed the issue in response to the Scottish Government's "national conversation" on independence.
The public sector union wants powers in areas such as equal opportunities, energy and broadcasting to be devolved.
On Friday, the Scottish Labour leader called for a constitutional commission to examine the devolution settlement.
Wendy Alexander said the body should consider introducing more tax-raising powers for Holyrood.
The SNP said her speech made a referendum on Scotland's future more likely in this parliamentary term.
At the meeting in Glasgow, Unison delegates from across Scotland backed further devolution from Westminster.
Its leaders believe there is potential for some powers to be transferred on immigration and public sector pensions, as well as extending powers over public borrowing and tax-raising.
The union urged other organisations who support the idea to join together and build a campaign.
Unison's Scottish convenor Mike Kirby said: "With the increase in the level of debate on this issue, we think that now is the time to begin to build a broad consensus of people and groups across Scottish society with similar aims.
"Devolution means that we should look at the powers of Holyrood from time to time.
"After two full terms of the Scottish Parliament, this seems like a good opportunity to do so, and we will be discussing with our branches and members what they consider could usefully be decided both in Edinburgh and more locally."
The Scottish Labour party will bring forward a motion in the Scottish Parliament this week to secure support for a devolution review commission.
