Nearly 70 healthcare workers with long Covid have taken their fight to the High Court to try to sue the NHS and other employers for compensation.
The staff, from England and Wales, believe they first caught Covid at work during the pandemic and say they were not properly protected from the virus.
Many of them say they are left with life-changing disabilities and are likely to lose income as a result.
The Department of Health said “there are lessons to be learnt” from Covid.
The group believe they were not provided with adequate personal protective equipment (PPE) at work, which includes eye protection, gloves, gowns and aprons.
