Employers are legally required to alert employees along with state and local officials at least 60 days before a mass layoff in what’s known as a WARN notice. Mattel submitted the notice Monday and said it expects affected workers will start leaving the company May 19.

Mattel, the toy company behind Barbie and Hot Wheels, filed a notice with the state to lay off 120 employees at its El Segundo headquarters in the Los Angeles area.
