The Irish Medical Organisation has condemned the HSE for what it claims is the poor treatment of junior hospital doctors recruited from India and Pakistan.
The union says it is aware of a number of doctors who have completed all necessary requirements to work in Ireland and are still not working nearly three months on.
The IMO says the doctors are "vulnerable, fearful and have no trust in anyone".
It says the issue is a humanitarian matter and internationally the HSE is bringing shame on Ireland.
The IMO says the doctors left the country, their families and jobs to come to Ireland to work and have been 'left in complete darkness as to what is happening'.
It also says the HSE should adopt the World Health Organisation's voluntary global code on ethical recruitment, which discourages countries from actively recruiting from poor countries facing critical staff shortages.
The HSE has responded saying 180 doctors from India and Pakistan have been registered with the Medical Council and have taken up their posts in Irish hospitals.
Around 280 were recruited for 190 vacancies in July.
The HSE said that the surplus of doctors recruited from India and Pakistan will help alleviate roster pressures and vacancies that would normally be filled by locums.
The HSE has said it is conscious that the duration and complexity of the registration process for the new division has led to frustration for some of the doctors who moved to Ireland to take up posts.
It said it was actively supporting doctors to ensure that they can get registered as quickly as possible with the Medical Council.
During the pre-registration period, the HSE has reimbursed travel costs to Ireland and provided accommodation and food for these doctors.
The Medical Council said: "Further information essential to the registration process is being submitted on an ongoing basis by both candidate doctors and the HSE and is being reviewed as a matter of priority."
The Medical Council said that there are 25 cases where the HSE has not provided the necessary declarations for doctors who came from India and Pakistan to be cleared to work here.
The Council said exams concluded in mid August and the HSE did not say at that stage that extra candidates would arrive here.
It also said the timelines for the registration of doctors recruited from India and Pakistan have been dictated by the HSE and candidate doctors.
It said there were also approximately ten cases where doctors have yet to provide the necessary documentation regarding training.
The seven exams organised to date were sat by 266 doctors and 30 failed.
The Council said it would stage more exams in agreement with the HSE.
But it has strongly advised doctors against arriving here before they have completed the first two stages of the registration process. These are: firstly, the HSE providing the necessary declaration, proposing a doctor for a specific post and secondly, provision of proof of qualifications and employment history.
After these steps are completed, candidate doctors then sit the clinical competence exam.
Indian doctor feels 'drained out'
An Indian doctor, who was recruited last December to come to Ireland, has told RTÉ News he feels "drained out financially, emotionally and socially".
After coming to Ireland in August, he and colleagues are still not working.
The doctor, who did not wish to be identified, said he was getting food and accommodation, but there were other costs he had to carry.
He said what had happened was not a proper way for a civilised and developed country such as Ireland to treat people.
He said he had resigned from a secure job in India to come to Ireland and had a young family at home.
He had responded to a HSE advertisement in December 2010 in India and did an interview there in early May.
The junior doctor said things that were promised did not come to pass when he arrived in Ireland, including pay levels.
Some doctors who were not working had to "walk to the local hospital in the rain" so they could eat in the canteen.
The doctor said that some other colleagues were in Ireland for two months and were still not working.
"I don't know when I will work," he added.
