Dear Ms. Matsunaga,
Thank you for posting your request on History Hub!
We searched the National Archives Catalog and located the Central Classified Files Relating to Hawaii, 1907 - 1951 in the Records of the Office of Territories (Record Group 126) that includes 12 file units pertaining to labor or strikes. For more information about these records, please contact the National Archives at College Park - Textual Reference (RDT2) at firstname.lastname@example.org.
Due to the COVID-19 pandemic and pursuant to guidance received from the Office of Management and Budget (OMB), NARA has adjusted its normal operations to balance the need of completing its mission-critical work while also adhering to the recommended social distancing for the safety of NARA staff. As a result of this re-prioritization of activities, you may experience a delay in receiving an initial acknowledgement as well as a substantive response to your reference request from RDT2. We apologize for this inconvenience and appreciate your understanding and patience.
We also searched the internet and located the Hawai’i Digital Newspaper Project by the University of Hawai'i at Manoa Library that includes a listing of all of the labor strikes in Hawaii from 1840s to 1946 and the various newspaper articles about them.
Lastly, we suggest that you contact the Hawai’i State Archives for additional information and resources.
We hope this is helpful. Best of luck with your research!
