Monsanto Monsanto Company 800 N. Lindbergh Boulevard St. Louis, Missouri 63167 Phone: (314) 694-1000 April 14, 1987 ENVIRONMENT. SAFETY 4 HEALTH Denise Oleske, Ph.D. Northwestern University Medical School W.G. Krununrich Study 215 E. Chicago Avenue, Suite 801 Chicago, IL 60611 Dear Denise: Enclosed are two items - a computer printout containing the frequency distri bution of jobtitles by department and year for four primary departments in the study and photocopies of union/management contracts that list the jobtitles for the same departments. The frequency distribution was created by combining the work records for all Monsanto employees (alive and deceased) who worked in departments 226, 236, A-236, 237, 268, and/or B-821. The numbers recorded in the frequency distribu tion represent the number of employees who held a specific job sometime during the year. Furthermore, the frequency distribution can be used to determine when each department began and stop operating and to determine the years that specific jobtitles were used. I have noticed a fair amount of agreement between the periods when the jobtitles were recorded in the union/management contracts and appeared in the frequency distribution, although it appears that the personnel office may have continued using some of the jobtitles even though they were no longer recorded in the union/management contracts. The photocopies of union/management contracts represent those years when the jobtitles changed in departments 226, 236, 237, and/or 268. Usually, the contracts were renewed ever two or three years, but the changes in jobtitles were more sporadic. I have also given a copy of these two items to NI0SH, hoping that it will benefit both groups in trying to reconstruct the history of the chlorophenol, pentachlorophenol, and 2,4,5-T esters units at the Krummrich plant.
