On checking last months pay discovered my basic pay was some £200 down. The system was supposed to make life easier by dividing annual pay into 12 equal installments, and they can't even get that right. It has been the same for the last 9 months so why a change now. The helpful?? people at JPAC haven't got a clue and said that there has been a slight glitch. Asking around our small unit found that 3 others also down by the same amount.
