there is this page where companies self report to the government when they will have layoff. in California the requirement is 60 days in advance. Found it here https://edd.ca.gov/en/Jobs_and_Training/Layoff_Services_WARN
Splunk is listed as going to layoff 174 more people on April 3rd 2023. Not sure if I am misunderstanding the data so please see it for yourself.
Good luck to all.
