Halliburton 2021 Annual & Sustainability Report Introduction 14 Employees With a diverse employee population representing multiple nationalities, we maintain regular employee engagement through a range of initiatives, including personal Check-Ins (Halliburton’s informal performance-management process), workshops, townhall meetings, performance feedback, employee resource groups (ERGs), and our biannual Employee Pulse Survey (EPS). These activities lead to an inclusive workplace in which employees feel their voices are heard no matter where they work. For more information about the EPS and the results of our August 2021 survey, which yielded our highest-ever response rate, please refer to Chapter S4 on Diversity, Equity, and Inclusion (DE&I) in this report. We use the information gleaned from this outreach to improve our workplace. Suppliers As a global provider of oil and gas services, we work with suppliers from all over the world and cultivate mutually beneficial, long-term relationships. We obtain feedback and ensure collaboration with suppliers on important matters, such as worker health and safety procedures, human rights compliance, and reduction of environmental impacts. Our communications with suppliers include meetings, workshops, and training sessions. Regulators We engage with government agencies and regulators that are responsible for developing regulatory standards that aim to protect the environmental, social, and economic fabric of the countries in which we operate. Our Halliburton Government Affairs group works alongside local operations management, government officials, and policymakers to provide in-depth information on our business; educate them on our technologies and products; and collaborate on issues that are important to our customers, employees, and other stakeholders. Government officials and policymakers often seek out our knowledge and experience on energy-related topics. Additionally, Halliburton supports foreign service offices, consulates, and embassies around the world as a technology and local content resource. Local Communities and Non-Governmental Organizations (NGOs) To support the global communities in which we live and work, we meet with community groups, nonprofit organizations, and NGOs to better understand their requirements and concerns. We give back to our communities through volunteer programs focused on environmental cleanup and awareness, education, health and safety, and social services. We also support community organizations through corporate donations and from our charitable foundations. Through these activities, we assist the economic and social well-being of our communities.
