The workers were suspended indefinitely without pay on Thursday. Today, Chrysler did not specify why they were formally terminated in a news release, only that the workers violated the company's standards of conduct.

"As is evidenced by the swift action taken in this matter, it should be clear that Chrysler Group will not tolerate such behavior and will continue to evaluate its protocols to ensure that something like this does not happen again," the news release reads.

The United Auto Workers condemns the use of alcohol and drugs on the job, and released its own statement to WJBK after the report aired.

"The employees involved in this situation do not represent the vast majority of workers at Chrysler who do a great job making high quality vehicles in some of the most productive manufacturing facilities in the United States," the union said.

"It is unfortunate that the actions of a few people have called into question the reputation of more than 51,000 very proud, hard-working Chrysler Group employees, grateful that the American and Canadian taxpayers gave us a second chance. We take that responsibility very seriously and will work to restore the public’s faith," Chrysler said in today's release.

Two other employees will receive a one-month disciplinary layoff without pay.
