Over 15 specialised Community Intervention nurses working in SouthDoc and 38 nurses working in Care Doc across the Midlands and the South East have yet to receive the payment.
The Irish Nurses and Midwives Organisation has described the situation as "completely unsatisfactory", and says members "feel extremely let down".
The INMO adds "these nurses put their lives at risk, like so many of their colleagues across the healthcare system did, when we knew so little about Covid".
