Unions say machines idle and suppliers unpaid at Mutares-owned La Rochette Cartonboard

The CGT, FO and CFTC unions at La Rochette Cartonboard plan a rally on 19 September 2026 outside the French cartonboard plant, denouncing unpaid suppliers, raw material shortages and idled machines despite a full order book. The 255-employee plant, with revenue of around EUR 90m, has been owned by German investment fund Mutares since 2021 and was previously part of Italy's Reno de Medici group.

Updates

  • 2026-09-18 · Edited before publication: The unions' allegations were carried as fact in the headline, and the source's note that management did not respond to requests for comment was missing, leaving the story one-sided. Headline reframed and the non-response added.
  • 2026-09-18 · Edited before publication: Passes the labour threshold because the unions allege a stated operational impact at a 255-employee, EUR 90m-revenue plant, but the headline led on the rally rather than on the most material claim. Rewritten to lead on the alleged stoppage while keeping it attributed to the unions. Both sides carried: management did not respond. Topics and materiality 3 stand.
