At ManTech, our success is a direct result of the dedication and values that we hold both individually and as a company, and we will remain steadfastly committed to these principles in the years to come.

Inclusion Programs

Our employees are at the heart of everything we do and that is why ManTech is the Employer of Choice for more than 9,800 highly qualified employees. They chose us in large part because our inclusive culture not only promotes, but relies upon, a workforce that is diverse in both its makeup and perspectives. Our success fundamentally relies upon inclusion and diversity to drive our core values and differentiate our business solutions. Each of our employees, from around the globe, brings distinct backgrounds and unique skill sets to the team, that set us apart. As One ManTech, we leverage our strength in inclusion and diversity to learn together, win together, and celebrate together.

A key element of the company’s strategy is to build a sustainable and enduring model that reinforces our inclusive workplace for the long term. ManTech is first and foremost a “people company”. Every solution, service and innovation we have developed and deployed is the work of talented people working together to leverage the power and capabilities of One ManTech.

Attracting and developing an industry-leading workforce is critical to our customers’ missions and to our success as a company. Our core values hold steadfast to our commitment to develop and ensure a diverse and talented workforce; one with a passion for mission success, intellectual capital, creativity and integrity.

To position ManTech for the long term — and a key element of our 2023 Strategic Plan — we will continue to evolve and develop workforce initiatives to reinforce diversity and inclusion as key components of our inclusive workplace. These initiatives will help ensure we are known as an employer that promotes and delivers equality in career opportunity and industry partnerships. The process started the Inclusion, Diversity, Equity and Accessibility (IDEA) project, designed to collect data and insight from all employees through a companywide survey, focus groups and stakeholder interviews. Together with our workforce we are creating a culture that enables every employee to become the best at what they do.

In 2021, senior ManTech women leaders launched the ManTech Women in Technology employee resource group to strengthen, encourage, educate, mentor and support the current and future generation of women in tech.

Scope of Supplier Standards

ManTech is committed to fair and ethical dealings with our teammates and suppliers and to the protection of shared sensitive and proprietary information that concerns company, customer, and supplier assets. We extend the protections and obligations of our standards to our suppliers, as required. We ensure competition among potential suppliers and we follow applicable government regulations and contractual requirements, including those pertaining to small and small disadvantaged businesses.

Suppliers are required to follow ManTech’s Supplier Code of Conduct (or a sufficiently comparable code of conduct of their own). This includes fair treatment and competition, adherence to laws and regulations, ensuring supply chain security, product and service quality, reporting of concerns and operating with integrity and honesty and a shared commitment to doing business the right way every day. ManTech monitors new and emerging risks and updates our practices and procedures accordingly, which suppliers and vendors are required to follow.

Supporting Small & Disadvantaged Business Teammates

ManTech’s 52+ year history is deeply rooted in its small business past. From a small business with one single contract, to a large business supporting many multiples of contracts, we are solving our customers’ complex challenges while fostering strong business relationships with the small business community. Entrepreneurship and the utilization of specially designated small businesses is essential to meet the needs of our Federal Government customers. We continuously seek subcontractors and suppliers to partner with to support customer missions. ManTech seeks maximum practicable opportunities to work with, and purchase from, small and disadvantaged businesses, including:

  • Small Business (SB)
  • Small Disadvantaged Business (SDB)
  • Women-Owned Small Business (WOSB)
  • Historically Underutilized Business Zones (HUBZone)
  • Veteran-Owned Small Business (VOSB)
  • Service Disabled Veteran-Owned Small Business (SDVOSB)
  • Historically Black Colleges/Universities and Minority Institutions (HBCU/MIs)
  • Alaska Native Corporations (ANCs) and Indian Tribes

Data Privacy & Security Policy

ManTech’s commitment to global security is steadfast and absolute. The trust and reliance of our customers and employees brings an enhanced obligation to protect their security and, by extension, our own. Our ongoing security focus renews and strengthens the high level of security around our people, operations and technology. At ManTech, the privacy and security of data entrusted to us by our customers, business associates and our personnel is of paramount importance. ManTech Secured also demonstrates our strong focus on doing business the right way — every day. Our security policies and practices make us government’s most trusted partner.

Whistleblower Programs

All ManTech employees complete annual ethics and compliance training to read and understand our Standards of Ethics and Business Conduct. Every ManTech employee has an affirmative duty to promptly report any actual or suspected violation of our standards or ManTech’s Policies & Procedures. All concerns reported in good faith and with sufficient detail will be evaluated and reviewed to determine whether a violation has occurred. If a violation has occurred, ManTech will take responsive corrective and disciplinary action, which may include termination of employment and the potential loss of security clearance. All suspected discrimination or harassment are reported to management, the Human Resources Department and/or the ManTech Helpline, regardless of who is involved (whether employee, consultant, vendor, or customer). ManTech will protect from retaliation each good faith reporter of suspected discrimination, harassment, and of evidence of gross mismanagement or waste, abuse of authority, substantial and specific danger to public health and safety, or violation of law related to a federal contract.

Employees receive training about how to make whistleblower complaints via our annual Ethics Training and all complaints are tracked until completion. Any type of concern – financial or nonfinancial – can be submitted. Third parties can file complaints through ManTech’s Ethics Hotline or by submitting their complaint via email or phone call to any HR representative or member of management. All actions taken can be reported out by the company.
