I haven't heard specifics as to level of management, but I was told 30-ish people were fired, with more layoffs coming.
This company is the most mis-managed of any I've worked for. Erratic hiring and firing practices. No security for anyone, really. This is especially discouraging given all the hype in 2016 about the $99 million Peace Coliseum. Most of us would be happy to work in a less fancy place and have a little job security.
