Health chiefs say they have carried out a recruitment drive to ease staffing issues at county hospitals and urged anyone with fears at being overworked to raise them.
Union bosses say underfunding of our hospitals - such as the Pilgrim in Boston - have left staff numbers too low and put too much pressure on workers.
United Lincolnshire Hospitals Trust says it has recently recruited to a large number of clinical posts for nursing and medical staff. It says inspectors from the Care Quality Commission praised the trust for filling posts.
A spokesman added: “We have carried out a review of the nursing establishment on all wards across all hospital sites in our Trust and are in the process of introducing a new staffing template which will provide an outline for required staffing levels on every ward. We also review staffing levels on our wards on a daily basis and respond to immediate daily needs.
“We actively encourage all staff to raise any concerns directly with the Trust. We have established processes in place to do this, and respond where issues are raised.”
Unite regional officer Dave Roome said: “Staffing levels in some areas are down on what my members consider are required resulting in some cases in very long hours being worked over shift patterns which are not conducive to effective working.”
