It was planned that this Wednesday morning the future of the historic Barcelona industrial company Serra Soldadura would reach a turning point. After Aernnova – owner of the company since 2008 – filed for voluntary liquidation bankruptcy to dissolve Serra Soldadura, this Wednesday the auction of the two companies that form it was scheduled. However, as union sources explain to ARA, the auction has been declared void after no potential buyer has come forward. "We didn't expect this," explain CGT sources, which holds the union majority in the company.
