You can see it on Kansas Works website. The link is below. Just enter Sprint in the search box and adjust the dates so it shows 2018 dates. Overall two notices have been filed, just about 500 layoffs have been reported - this is in line with what got reported to the media and what the execs have been telling us for a while now.
I am not approving these layoffs and execs could have handled it much better but all what I am saying is that it's not as secretive as some folks on this site contend.
