An estimated 6,000 members of the Psychiatric Nurses’ Association began their overtime ban at 7am today, in line with their dispute with the Health Service Executive.

Their union stated that there had been a lack of progress with the HSE in what they claim are ongoing and worsening staff shortages.

In response, they are refusing to work any overtime.

The HSE have said that the action will have a negative impact on the delivery of care to patients.
