29 CFR 779.217 : Labor (§ 0.735-1 To Parts 4908-4999) — (§ 500.0 To Parts 871-899) — Regulations Relating To Labor (Continued) (§ 500.0 To Parts 871-899) — Wage And Hour Division, Department Of Labor (§ 500.0 To Parts 871-899) — Statements Of General Policy Or Interpretation Not Directly Related To Regulations (§ 775.0 To § 794.144) — The Fair Labor Standards Act As Applied To Retailers Of Goods Or Services (§ 779.0 To § 779.515) — Employment To Which The Act May Apply; Enterprise Coverage (§ 779.200 To § 779.269) — Unified Operation Or Common Control (§ 779.215 To § 779.224) — “Unified operation” defined.

Webster defines the word “unify” to mean “to cause to be one; to make into a unit; to unite.” The pertinent definition of “operation” is a method or way of operating, working or functioning. Since the term “unified operation” has reference to the method of performing the related activities, it means combining, uniting, or organizing their performance so that they are in effect a single business unit or an organized business system which is an economic unit directed to the accomplishment of a common business purpose. The term “unified operation” thus includes a business which may consist of separate segments but which is conducted or operated as a unit or as a single business for a common business purpose.
