It’s technology that's used to make microchips, which are a major component in modern vehicles, phones and thousands of electronic devices.

Unifor Local 444 president Dave Cassidy tells AM800 News it's a global shortage, so Windsor Assembly Plant will be fighting for parts with some major manufacturers.

He calls the shutdown a "tough blow" to workers at the plant and hopes to have more information after he speaks to Stellantis on Friday.
