The Labor Board FYI

Catlettsburg Refining

The rule for this page

This page gathers every case where the Board's own filer wrote "d/b/a Catlettsburg Refining" or "a franchisee of Catlettsburg Refining", or a close variant of those words, on the case name. It is not this site's own judgment that these employers share a brand; it is what the filer wrote. Whether a franchisee and the brand it names are one employer for the Board's purposes is not something this record settles.

24 cases here, under 3 employer names.

The Labor Board FYI is independent, and is not the Board or any government agency. Where a number here disagrees with the Board's, the Board is right: tell us at [email protected]. If a name here is a private person and not a business or a union, write to the same address and it comes off. Where this comes from.
