Spain's largest union said on Friday it was not satisfied with the details of government labour reform proposals leaked to the media so far and that a general strike "seems inevitable", according to Reuters. Labour unions have called a one-day public sector strike on Tuesday against government austerity measures which include a public sector pay cut, and have threatened a general strike if they are not happy with the government's labour reform package. The government has said it is proceeding with its own version of labour reform as months of talks with unions and business leaders have failed to produce a consensus, and that it will present the plan to the other parties on June 9. Union leaders met on Friday and "reiterated their rejection of the austerity plan as unjust, unbalanced and bad for the economy, along with some of the contents that have emerged on labour reform," trade union Comisiones Obreras (CCOO) said in a statement. "We have put into place preparations to call a general strike, which seems inevitable," the statement said. It is unclear how successful such a call would be given that the unions represent only about 16 percent of the labour force. The union said it was preparing a campaign to explain its position to the public.
