UAW officially filed its "formal objection" to General Motors announcing plans to close plants in Michigan, Ohio and Maryland with new statements from its president and vice president on Monday, Dec. 3.

In all, the Detroit-based automaker plans to close the Detroit-Hamtramck Assembly Plant, Lordstown Assembly Plant in Warren, Ohio and Oshawa Assembly plant in Ontario, and two propulsion plants in Michigan and Maryland by the end of 2019.

"We have been clear that the UAW will leave no stone unturned and use any and all resources available to us regarding the future of these plants. Today, we wrote to GM formally objecting to its unilateral decision regarding four U.S. manufacturing facilities," UAW President Gary Jones said in a statement.

"There are issues related to this and to collective bargaining that we cannot discuss in detail at this point. But UAW members across this country are committed to using every means available to us on behalf of our brothers and sisters at Lordstown, Hamtramck, Baltimore and Warren, MI. UAW members and U.S. taxpayers invested in GM during their darkest days. Now it is time for them to invest in us!"

The automaker says that the closure of these plants will increase its cash flow by $6 billion by the end of 2020. The Associated Press reports the move will see 14,700 employees laid off, including 8,100 salaried, white-collar workers.

Last week in the aftermath of the announcement, UAW called GM's decision a "callous" one that was "profoundly damaging to our American workforce." In his statement at the time, Terry Dittes, UAW vice president and director of the GM department, said GM's "decisions are a slap in the face to the memory and recall of that historical American made bailout."

"This issue impacting our members, their families, the communities and all of America is much more complicated due to the known fact that GM is a major importer of their brands from China, Canada and Mexico that are sold in the United States," Dittes said in his most recent statement on Monday.

"Versions of the Chevy Cruze and Impala are assembled in Mexico and Canada respectively and imported to the U.S. and those two vehicles are also assembled at Lordstown Ohio and Detroit Hamtramck Plant here in the USA."

President Donald Trump has echoed UAW's statements in expressing his disappointment in the stateside cutback in light of the government bailout. Before threatening to cut all subsidies to GM, Trump warned that the automaker was "playing around with the wrong person."

Most recently the president said what the Detroit-based automaker is doing is "very counter to what other auto, and other companies are doing."

Mary Barra, the automaker's CEO and chairman, said that these measures will continue GM's transformation into a "highly agile, resilient and profitable" company with some needed investment flexibility. Also as part of the cuts, GM will also cease production of the Chevrolet Impala, Volt and Cruze, and is also thought to be eyeing the Cadillac XTS, CT6 and Buick LaCrosse for the chopping block.

"GM is committed to maintaining a strong manufacturing presence in the U.S., as evidenced by our more than $22 billion investments in U.S. operations since 2009. Yesterday's announcements support our ability to invest for future growth and position the company for long-term success and maintain and grow American jobs," the automaker said in its own statement touting its commitment to the U.S. and Midwest.

"Many of the U.S. workers impacted by these actions will have the opportunity to shift to other GM plants where we will need more employees to support growth in trucks, crossovers and SUVs. GM's transformation also includes adding technical and engineering jobs to support the future of mobility, such as new jobs in electrification and autonomous vehicles."
