The directive was communicated to newsmen through the office of the Head of the Civil Service of the Federation, Mr Danladi Kifasi.
In the circular, the Presidency emphasised the urgent need to compile the names of those being owed so as to pay them immediately.
The Presidency also directed the MDAs to ensure the accuracy and verification of each unpaid entitlement while details to be presented must also include the name, designation, status (serving or retired) and amount due to each officer.
“The correct information should reach the Office of the Head of Civil Service of the Federation on or before Monday, September 21 2015,” the circular emphasised.
Reacting to the directive, secretary-general of Association of Senior Civil Servants of Nigeria, Mr Alade Lawal, commended President Muhammadu Buhari “for bringing hope to thousands of public service employees who were being owed arrears of salaries and allowances for years.”
