C8 Z06s have been held up in being shipped since mid August yet GMs answer to this is to blame the UAW strike that started weeks later

GM now states :

“The industry continues to experience temporary parts shortages due to a number of circumstances.
Bowling Green has been impacted by this, so we have taken steps to keep production running to meet continued strong demand.
As a result, we are building some vehicles without specific parts and will retrofit those vehicles as the parts become available before they are shipped to customers. We are working to resolve these issues as soon as possible.”

--------------------------------------

So, Chevrolet is citing parts shortages as the culprit for the delays.
However, the statement keeps things ambiguous and stops short of pointing a finger at the UAW strikes as the cause of said parts shortages. Despite being nearly three years removed from the global pandemic, could the automotive industry still be feeling the ripple effect?
Or is Chevrolet remaining diplomatic in the face of the strikes?
We can see one or both of these factors being absolutely true. Unfortunately, none of that will help the Z06 owners in waiting get their cars any faster.

Canadian autoworkers union Unifor said it has set an Oct. 9 deadline to reach a tentative agreement with General Motors.
"Unifor informed GM that the union has set a negotiating deadline for Monday, October 9 at 11:59 p.m.," officials said Thursday in a bargaining update on its website.
The announcement comes about four days after its members ratified a historic contract with Ford Motor Co.

Union officials said Thursday that "bargaining committees are now focused on locking in the pattern agreement at General Motors."
All the significant increases to pensions, wages, health benefits, and more must now be bargained with the company," the statement said.

"The gains negotiated in the pattern include the best wage package ever negotiated in the union’s history, as well as reducing the grow-in from 8 years to 4 years, a $10,000 productivity and quality bonus for full-time employees and a $4,000 bonus for 'temporary part-time employees.'

"There is a lot of work to do, and we have confidence that our bargaining team is up to the challenge."

Unifor’s negotiations with GM cover approximately 4,300 workers at the St. Catharines Powertrain Plant building engines for the Chevrolet Equinox and Corvette, Oshawa Assembly Complex making light- and heavy-duty Chevrolet Silverado pickup trucks and parts for other vehicles, and the Woodstock Parts Distribution Centre in Ontario.

The Canadian union representing General Motors Co. workers at three plants called for a strike against the automaker early Tuesday.
Unifor called for the work stoppage against GM shortly after 11:59 p.m.
Monday deadline it had set earlier to reach a tentative agreement with the company.

Unifor’s negotiations with GM cover about 4,300 workers at the St. Catharines Powertrain Plant building engines for the Chevrolet Equinox and Corvette, Oshawa Assembly Complex making light- and heavy-duty Chevrolet Silverado pickup trucks and parts for other vehicles, and the Woodstock Parts Distribution Centre in Ontario.

Unifor's strike against GM was called on day 26 of an unprecedented strike by the United Auto Workers representing American autoworkers at GM, Ford Motor Co. and Stellantis NV. GM-UAW members are on strike at the Wentzville, Missouri, midsize truck plant, the Lansing Delta Township Buick Enclave and Chevrolet Traverse plant and all of GM's Customer Care and Aftersales facilities. In total, about 9,200 UAW-represented GM employees are on strike in the United States.

Unifor's strike was called after Unifor President Lana Payne on Friday told members the two sides remained at odds over several issues because GM wasn't agreeing to follow aspects of the pact Unifor got with Ford.
Late last month, Unifor/Ford members ratified a new three-year deal that included the single largest negotiated general wage increase in the history of Unifor, formerly the Canadian Auto Workers.

The deal offered increases of 10% the first year, 2% the second year and 3% the year after, as well as cost-of-living adjustments. It also reduced the amount of time an in-progression employee needs to reach the top pay scale from eight years to four.
For those workers who haven't reached top scale, it raised the percentage those workers get in the first three years.

One issue Payne mentioned on Friday was that GM was resisting transitioning full-time temporary workers to permanent-employee status. GM was also seeking a lower universal healthcare allowance for retirees than the quarterly allowance Ford agreed to, Payne said.

Payne also noted that Unifor had not received anything confirming the existing programs and future programs GM has announced, including next-generation pickup trucks at Oshawa and electric drive units at St. Catharines.
Payne said at the time, Unifor expected "to see these commitments in writing and in the collective agreement. GM knows this, but there have been no advancements on this front to date."
