The WARN notice is mandated by US labour law and requires companies with 100 or more employees to provide 60 days advance notification of plant closings and mass layoffs.
The notice stated that the lay offs will occur between April 13 and April 30. (http://on.ny.gov/1OHqddE) Earlier this month, the US cable network shut down less than three years after its high-profile launch.
As of last summer, the network had about 800 employees, according to one former employee who asked to remain anonymous.
The news outlet said it will cease operations by April 30, citing economic challenges in the American media market.
Al Jazeera, which is owned by Qatar-based Al Jazeera Media Network, had been trying for years to break into the US cable market when it bought Current TV, a US-based television network owned by former US Vice President Al Gore and his business partner Joel Hyatt, for $500 million in 2013.
The network hired some well-known television journalists, including Soledad O'Brien and Ali Velshi from CNN, and generally has been given high marks from journalism experts for its coverage. Yet, with its Arabic name and Qatari pedigree, the network continued to struggle to find a place in the US media landscape.
