Three workers from St Leonard's Hospice were sacked and several others demoted after the 2021 visit.
An MP has criticised the "harsh" treatment of hospice staff caught breaching lockdown restrictions.
York MP Rachael Maskell said people had since told her of concerns about the hospice, and management should have considered alternative solutions.In May last year, around 20 staff from the hospice gathered in a York pub garden, hours before restrictions were due to be eased. Care assistant Angie Pollard, who had worked at the hospice for nearly twenty years, was one of those to be dismissed for breaching the rules.
The loss of experienced workers had made ongoing staff shortages worse, colleagues told BBC Look North, with the hospice currently running at about half the pre-pandemic level for in-patients.
