Thanks for the replies. It is a large organisation and have been working on the internal bank for the past five or six years. One assignment lasted to two and a half years another one lasted eighteen months. During a period of unemployment, I contacted the bank on a number of occasions and was told they had no assignments. However an outside agency contacted me with the offer of a position at the said organisation. On contacting the organisation to give them my details she was told that they did know me, and I had worked for them before but they wouldn't use my services again. Naturally I was devastated. I have recently been told by the agency person that during a recent meeting with one of the managers my name came up and the manager said that I was disruptive, that there was nothing wrong with my work. I would really like to get to the bottom of what's happening.
