I work as an IT Consultant, the programme I work on decided to employ Ernst Young consultants and release a lot of us early from our contract and gave 2 weeks notice. On 24th May I was told my contract was finishing early, but he said I could bill to the end of may and bill 2 weeks of June to cover the notice period. I submitted 2 time sheets one for the month of May and the other for the 2 weeks in June, these were duly approved and returned to me copying in the Finance Manager who was present during the meeting, raised invoices to cover the time-sheets and submitted to my agency. I have now been told by the agency that the company is refusing to pay my May time-sheet as I had finished on the 24th May, I spoke to the person who authorized the time-sheet who was one of the people in the meeting and he confirmed his interpretation was the same as mine. I explained to the agency that I will not amend the invoice as it is in line with the discussion I had and reflects an approved time-sheet. Yesterday I received an email from the agency with a copy of my time sheet this time altered and they said they would now only accept an invoice based on the altered time-sheet. I intend to stick to my guns but would appreciate any views from you chaps in respect of where I stand. My opinion is that if I accept a retrospective amended time sheet that I have not agreed to that replaces a previous time-sheet that was properly authorized there is nothing to stop them doing that to any time sheet have submitted. Grateful for any views.
