The suit asks the Oregon U.S. District Court to grant the aggrieved employees back pay and allow them to recoup lost benefits.

"Defendant abruptly terminated several groups of employees, unilaterally and without proper notice to employees or staff, terminating over 50 employees and at least 33% of active full-time employees, including Plaintiff, at the Facility," the lawsuit reads.

In a notice sent to state of Oregon and city of West Linn officials on Aug. 6, company President Brian Konen said the 60-day notice requirement did not apply because of the "difficult circumstances faced by the faltering company."

The lawsuit however alleges that "no circumstances existed that would have permitted Defendant from reducing the notification period as provided in 29 U.S.C. § 2102(b)."

Konen did not immediately respond to a request for comment.
