What does unionisation mean?
Unionisation is the process of forming or joining a trade union, or of organizing workers collectively in such a body. It is especially associated with industrial relations: workers join together to negotiate pay, hours, conditions, and job protections, often through an elected committee or recognized union. The word is neutral in its basic meaning, though in political debate it can suggest either workplace solidarity or conflict between organized labour and employers. In everyday reporting, unionisation may refer to a campaign at a particular workplace, while in broader historical discussion it can describe the growth of organized labour during industrialization. British English generally spells the word unionisation, whereas US English uses unionization, with the same meaning. Because the concept is broader than the existence of a formal union, it can also refer to efforts to establish union representation where none previously existed. The term is therefore useful for describing not only a finished organization but also the collective process through which workers gain a stronger voice.

Where does unionisation come from?
Unionisation was formed within English from union and the suffix -isation; in the US spelling, the suffix appears as -ization. Union descends through French from Latin ūniō, meaning “one” or “single,” ultimately from ūnus, meaning “one.” The same Latin source underlies unite, unity, unit, and unison, while the modern trade-union sense developed as organized labour expanded during industrialization.
