Is it permissible to benefit from the Ministry's personal resources (such as stationery, ink, telephone, and other materials) as compensation for the loss of previous rights (such as promotion and allowances) resulting from negligence in calculating years of experience?

You have the right to demand that your experience be recognized and to clarify this to the officials. However, taking work items is not permissible, and you must prove your right and then demand it. Your acceptance of the work without recognition of your experience is considered a dereliction on your part, and you can remedy this by refusing to renew the contract or by demanding that the officials review the matter.
