The UGT and CCOO unions at Spanish energy giant Iberdrola called a nationwide strike for June 19 on Monday, demanding that wages be adjusted for inflation.

Approximately 9,000 workers have been called to strike to pressure the company into accepting union demands within a new collective bargaining agreement.

o The two unions are seeking inflation-linked pay reviews and a reduction in working hours, among other grievances.

o This would mark the second nationwide strike in the company's history, following last year's walkout over pay issues.

o UGT representatives stated that Iberdrola workers' wages have fallen by 19% in real terms over the past five years.

o The company remains open to reaching a balanced agreement, an Iberdrola spokesperson said.
