Protesting Parliamentary Staff Association of Nigeria (PASAN) members have crippled all activities at the National Assembly (NASS) as power supply to the complex has been cut off.
The workers commenced a four-day warning strike on Monday, barricading the National Assembly Complex in the early hours of the day to prevent entry.
Supply to the Account Section of the Annex was however spared with the workers allowed to do their work of preparing the next salary for the workers.
Water supply to the complex was also stopped.
At about 10am, the union leaders forced workers on duty at the Engineering Department to cut off power supply to the complex.
About 30 minutes later, all the banks, telecommucation offices, resturants, other supporting staff, including the Radio Nigeria studio within the complex closed down and their workers departed and seen trekking the long way back to the car park wearing long faces.
