Approximately half of our workforce is represented by unions. We work with our represented employees to build collaborative and mutually respectful relationships. We recognize that all parties benefit by working together to achieve mutual goals. Interim bargaining has been used for the past 15 years to improve union relations and promote collaboration. We hold regular meetings between management and labor unions in order to address grievances and avoid arbitration when possible. We asked our bargaining unit employees to help us address financial challenges during their normally scheduled negotiations and as allowed under their current collective-bargaining agreements.
While each collective bargaining agreement is negotiated with a specific local union, we include equal opportunity clauses in all our bargaining contracts. We also operate in compliance with the policies of the National Labor Relations Board, the statutes of the National Labor Relations Act and the guidance of the Department of Labor.
We published our first corporate responsibility report (formerly known as the Triple Bottom Line report) in April 2005, with the contents covering the 2004 calendar year, and we have published a similar report in each following year. Our report is based on Global Reporting Initiative (GRI) G3 Sustainability Reporting Guidelines, the most widely used sustainability reporting framework in the world. Additionally, we incorporate the GRI’s Electric Utilities Sector Supplement indicators wherever possible.
