(a) All persons employed by the County or by any of its boards, whether as officers or otherwise, and paid either in part or in whole from appropriations made by the County Council, except those whose compensation is fixed by state law, shall be compensated only in accordance with pay plans adopted by the County Council.
(b) Not more than 15 days after receipt from the County Executive of any recommendation of measures for the establishment or amendment of a pay plan or portions thereof, the President of County Council shall introduce an ordinance for the adoption of such recommendations. Not later than 60 days after the receipt of such recommendations, the County Council shall adopt them as submitted or in such amended form as the County Council shall provide. Should the County Council fail to act upon such recommendations within such 60-day period, its approval shall be presumed and the recommended pay plan or amendment thereto shall become effective as recommended.
