Rumors have been flying that Island Def Jam is laying off roughly 40 individuals by week's end. While Billboard has not been able to confirm a total number, a few layoffs were carried out Monday and Tuesday of this week, including: Crystal Issacs, senior national director of mixshow promotions; Ray Romulus, A&R manager; one member of the creative department; one artist development person; and the entire Roc La Familia staff, which serviced Def Jam's international arm. More lay-offs are expected as the week continues.
