Maternity support staff strike at Grimsby hospital
They're walking out in a row over pay
Maternity support workers at Diana Princess of Wales hospital in Grimsby are set to strike this morning for two weeks.
It's the third time this year they're on the picket line.
The dispute is over wages.
UNISON says they've not reached an agreement for their previous underpaid work.
We've been speaking to Ashley Harper from the union.
He told us: "They have now got that new band and that's great and it's finally been recognised but it's about trying to get fair back pay."
Potentially somebody with nearly 40 years service can come out with less back pay than someone with 4 years service
"I think the message from our members is they don't feel they're listened to by the Trust and don't feel they're being treated fairly."
"The proposals they've got at the moment - they don't properly reflect people's experience."
"It's leading to this quite bizarre situation that can arise where potentially somebody with nearly 40 years service can come out with less back pay than someone with 4 years service."
"We've seen figures to indicate that."
"Those colleagues with 4 years service - they should get what's on the table for them - it's just making sure that others with much more service don't come out worse than them."
"It's not fair".
The Trust says talks are still ongoing and they remain committed to reaching a resolution with Unison
"We're always conscious about this - we're a responsible union - it's the health service."
"None of our strike action is ever designed to cause any harm and the Trust will be putting measures in place - they'll get cover."
"They'll have to make sure there's additional mid wives there to cover out members there - that will happen."
A spokesperson from the Trust says they are prioritising the safety of expectant parents and babies in our care - with plans put in place to maintain safe services during this period of industrial action.
They also say talks are still ongoing and they remain committed to reaching a resolution with Unison
