In September, 17,700 workers were on strike, mostly the now settled writers' strike. Ended strikes give a boost to the employment report (this was a few thousand in September).
This number will be closely watched in October with the UAW strike. The Kaiser strike (75,000 workers) is scheduled for just 3 days and will not impact the October employment report.
Note that the reference week for October is next week.
A good example of the impact of a strike on the employment report is the AT&T strike in 1983 when 675,000 workers were on strike in August 1983. The BLS reported job losses of over 300 thousand in August, and then a gain of over 1.1 million in September when the workers returned.
The Strike Report will be important to check on Friday, October 28th.
