Staff at Liverpool museums are to meet with councillors and MPs in a bid to bring a pay dispute to an end.
Museum staff say they feel they are being exploited
Union members claim a pay offer by museum managers was refused as it was below the rate of inflation, but bosses claim the deal was "reasonable".
Three one-day strikes have already been staged but union representatives claim management are still refusing to find a way of resolving the dispute.
Members of the Prospect union are meeting with officials on Monday night.
Union leaders say they have now reached an impasse after a number of strikes.
They claim they are being "exploited" as they are being asked to promote the city's image while effectively taking a pay cut.
The aim of Monday's meeting is to make the position of Prospect members clear and find a solution before Liverpool becomes European Capital of Culture.
