This study was conducted by Center for Trade Union and Human Rights (CTUHR) between December 7, 2012to March 2013. Personal interviews, focus group discussion and interview of key respondents through email were used to gather data. Twelve worker-leaders from Agusan Plantation Inc.

(FPPI) participated in the focus group discussions while five key informants were interviewed: three were conducted in person and two were done through emails. CTUHR also visited and interviewed organizations in Misamis Oriental involved in the campaign against A Brown expansion in Opol, Misamis Oriental. In addition, CTUHR also used existing documentations on several incidents/cases involving the four companies.
