Brazilian nongovernmental organizations (NGOs) with missions centered on the sustainable preservation of land, water, forests, and other environmental factors have garnered much attention because of rapid deforestation in the Amazon, global concerns about the ozone layer, water and energy issues, and effects on indigenous ways of life and knowledge as well as the Brazilian economy (Correia, 2016). With publicity and events surrounding the 2016 Olympics, reports celebrated the human and bio-diversity in Brazil but also displayed the poverty, political instabilities, and crime in Brazil, as well as consequences of the Brazilian Zika virus (Cugola et al., 2016). With such broad and deep opportunities and needs in Brazil, NGOs feel pressures from diverse sectors and challenges inherent in the meanings and conduct of sustainability work itself.Specifically, Brazilian NGO and global professionals engaging in sustainability efforts, find that they must manage tensions in their political positions, social practices, and daily activities (Fátima do Carmo Guerra, dos Santos de Sousa Teodosio, & Mswaka, 2016;Mackin, 2016; see Mitra & Buzzanell, 2017). These tensions are symbolic as they enact work that they perceive to be meaningful but frustrating, and material as they seek impact through short-term deliverables but struggle with long-term solutions within complex interdependent human and material systems (Fátima do Carmo Guerra et al., 2016;Mitra & Buzzanell, 2017). Tensions also emerge in their internal and external ethical responsibilities, including their communicative labor.According to Mumby (2016; see also Carlone, 2008), communicative labor refers to processes of mutuality, authenticity, and affect through which people share experiences. Applied to branding, communicative labor is key to the creation of value in work, production and consumption, and erosion of personal life through emphasis on labor (Mumby, 2016; see also communicative labor affirming hard work as virtuous, in Dempsey & Sanders, 2010). Applied to NGOs, Dempsey (2009) explores how grassroots organizations, particularly environmental justice and sustainability NGOs, engage in communication labor, defined here as the creation of distinctive organizational identities 709325S GOXXX10.
