The Unite union representatives have told ITV News a 10 day strike will begin on the 27 January, running till the 5 February, unless a deal can be struck.

Coming at the end of a seven day walkout, the 650 workers on Teesside, North Yorkshire and County Durham, say they want a £1 per hour pay rise backdated to March 2018.
Arriva North East has rejected this request, instead offering a 75p per hour pay offer over two years, in four instalments.
The drivers in question operate in and around Darlington, Durham, Redcar, Stockton and Whitby.
Union bosses and company managers are due back at the negotiating table again on Thursday as both sides seek an agreement.
Arrive North East bosses say the industrial action is of real concern and is putting the company at risk.
