STAFF at Grimsby's Diana, Princess of Wales Hospital will walk out on Monday as part of a national strike over pay.
Members of the Unite, Unison and GMB unions will go on a four-hour strike between 7am and 11am.
They will be joined on the picket line by members of the Royal College of Midwives (RCM), who voted to take strike action for the first time in its 133-year history.
The walkout is set to disrupt non-essential ante-natal and post-natal appointments and could result in some elective operations being cancelled.
However, the hospital's accident and emergency department, theatres, hyperacute stroke unit, high dependency unit, intensive care units and oncology services will all be running as normal.
Midwives will still be there for mothers giving birth.
Wendy Booth, head of performance assurance at Northern Lincolnshire and Goole NHS Foundation Trust, said: "Preparations are underway to ensure that contingency plans are in place ahead of the national strike next week.
"We are currently negotiating with the unions to secure some exemptions to the strike – areas where we care for our most high risk patients.
"We are doing everything we can to ensure that disruption to patients is kept to a minimum. Maintaining the safety of patients is our top priority."
"At this stage we are unsure exactly what effect the strike action may have, but are planning to ensure that patients needing treatment during the period will be seen and treated appropriately, and that patients already staying with us continue to receive the quality treatment that they expect and deserve.
"Patients who do not hear from us and have appointments for that day should attend as usual."
Hospital employees are protesting over the rejection by the Government of the Independent NHS Pay Review Body's recommendation of a one per cent pay rise for staff.
Suzanne Miller, the RCM's regional officer in our area, said: "Members in Grimsby voted overwhelmingly in favour of the strikes and have decided that enough is enough, midwives and all NHS staff work extremely hard often putting in hours of overtime out of their own good.
"It's estimated that midwives put in almost 13 extra overtime hours on top of what they already do and the one per cent pay rise we asked for is equal to those 13 hours. It's about time they were paid for them.
"This overtime keeps the NHS propped up and its about time they were recognised for that."
Paul Swarbrick, area organiser for Unison, said its members were "disgusted" that the one per cent pay increase had been rejected.
He added: "Over the past five years, staff pay in the NHS has gone down about 12 per cent in real terms. A one per cent increase is not enough but it's a further kick in the teeth that 60 to 70 per cent of staff are not getting it anyway.
"There will be no compromise on patient safety. If there are any major incidents our members will come off the picket lines."
Local government workers were due to take strike action on Tuesday, but this has now been suspended so that Unite, Unison and GMB can consult its members on proposals to increase pay for the majority of workers by 2.2 per cent.
