UPDATE, 6 p.m. - The district says in a press release that 3,024 employees total will be given layoff notices. Among those, 1,523 are teachers and 490 are central office staff. Layoffs began today and will continue.
Site selection - planned for Wednesday after school - is still on for now, but the district's General Counsel is reviewing, a spokesman said.
UPDATE, 4:05 p.m. - An injunction has been issued, and layoff notices for 1,500 teachers are rescinded at least until a June 14 hearing, reports my colleague Troy Graham, who was inside the courtroom.
UPDATE, 3:30 p.m. - PFT President Jerry Jordan is waiting to be heard on a temporary restraining order to halt layoffs. Jordan says that the PFT is aiming to stop the "erroneous" exemption of Promise Academy teachers from layoffs. "That's a violation of the contract," Jordan said.
Jordan said he was told the proceedings were delayed because the district is waiting for an outside attorney - not an in-house district lawyer - to come and argue the case.
UPDATE, 2:40 p.m. - PFT President Jerry Jordan is at this moment filing a lawsuit over the district's layoffs, a union official confirms. Will bring you updates as I have them.
UPDATE, 11:15 a.m. - I'm told that layoff notices at central office have not gone out and it's not clear when they will. At schools, a few principals have already begun notifying teachers; most are waiting until the end of the day.
Also, Councilman Bill Green today sent Mayor Nutter a letter about his demands for accountability from the school district. Read my City Hall colleague Troy Graham's blog post about that letter - and the letter itself - here.
EARLIER: It’s the start of an incredibly crucial - and difficult - week in the Philadelphia School District. As my colleague Troy Graham reports here, Mayor Nutter yesterday sent this letter to the School Reform Commissioner and Superintendent Arlene C. Ackerman demanding a better accounting of how the district spends its money and more say-so. The mayor set Thursday at noon as a deadline for gaining a new “education accountability agreement.”
