FRANKFURT: Stefan Wittmann, who sits on Commerzbank's supervisory board as a labour representative, said on Friday that plans to cut 10,000 jobs were "simply crazy".
Wittmann's comment to Reuters came as the board embarks on discussions about a radical overhaul proposed by management.
Wittmann, an official with the Verdi labour union, said doing more with fewer people is not a recipe for success in the long term.
A spokeswoman for Commerzbank declined to comment.
