A ship can be an establishment for redundancy purposes, the Court of Appeal ruled on 13 December 2018.
For large scale redundancies, there is a duty to consult the workforce of the establishment under Trade Union and Labour Relations (Consolidation) Act 1992 s188.
This case concerned a shipping company based in Farnham, Surrey. The Court held that each ship was an establishment, and that it had sufficient connection to Great Britain to bring it within the Act.
