DETROIT, Sept 17 (Reuters) - The United Auto Workers

union plans to hold strike authorization votes at one or more of

its Stellantis ( STLA ) local chapters in the coming days,

union president Shawn Fain said on Tuesday, which could lead to

a disruptive walkout against the Jeep maker.

The UAW leader has in recent months called out Stellantis ( STLA )

CEO Carlos Tavares for failing to keep the product and

investment commitments the automaker agreed to after the union

conducted a six-week strike last autumn.

"We are still waiting for the company to make good on the

vast majority of its product commitments. Not all of them are

contract violations yet. But we're watching them closely and

we're preparing to take action," Fain said in a video address on

Tuesday evening.

Local Stellantis ( STLA ) chapters have filed grievances related to

the company's alleged plan to move production of the Dodge

Durango out of the United States, union leaders said this week.

The union on Monday also filed unfair labor practice claims

with the National Labor Relations Board against Stellantis ( STLA ),

saying the company refused to provide information about its

future product plans.

Representatives for Stellantis ( STLA ) did not respond to a request

for comment.

Fain also reiterated his anger around the company's delays

of a planned multi-billion dollar investment into a new battery

plant and factory in Belvidere, Illinois.

Securing jobs at the Belvidere plant was one of the

union's most prized victories after its nationwide strike

against Stellantis ( STLA ), Ford Motor ( F ) and General Motors ( GM )

late last year, and a symbol of the labor group's ability to

protect union jobs as the industry shifts to producing electric

vehicles.

The UAW also won a record 25% general wage increase, the

return of cost-of-living adjustments, and the right to strike

over product commitments and investments, the latter of which

Fain said allowed them to hold a walkout against Stellantis ( STLA ) now.
