From The Jakarta Globe:
Trade unionists at state electricity company PT Perusahaan Listrik Negara are seeking a judicial review to overturn the new electricity law, which will finally open up the power market in to private sector competition. The union, which said it will apply for a judicial review at the Constitutional Court today, claims the law is unconstitutional because it will benefit foreign investors, while driving up the price of electricity.
The article goes on to discuss the issue of privatization itself more than how it will effect the PLN union and its workers. For a more comprehensive analysis of the PLN’s fight against privatization, I suggest this blog post by Indah Budiarti on the issue.
