MPC filed a Worker Adjustment and Retraining Notification (WARN) with the South Dakota Department of Labor & Regulation, according to the DLR's public reporting page.
The filing describes a workforce action in North Sioux City, per a notice the DLR received Jan. 2, 2009. The notice does not state when the workforce action takes effect. 45 employees are affected.
The federal WARN Act requires employers with 100 or more full-time workers to give 60 days' notice before a plant closing or a mass layoff — job losses at a single site affecting either 50–499 employees who make up at least 33% of that site's workforce, or 500 or more employees regardless of percentage.
Employers sometimes file WARN notices voluntarily or amend earlier notices; this filing on its own does not indicate the notice was federally required.
The records published so far include 1 earlier record whose employer name is the identical string "MPC", the earliest dated Nov. 5, 2008. Every notice here names the same employer, exactly as the Department of Labor & Regulation typed it on the filing. That counts only the published records, not what the source holds.
This section is assembled from other records already published and from arithmetic on the date above. No coordinate is involved: these records are matched by the place their sources name, not by distance. It is not part of the filed record.
