Schultz went on to address actions he said would "ensure you are clear that we will neither stand by, nor stand silent, as the uncertainty around the new administration's actions grows with each passing day."
One of these, he said, would be to hire more refugees. "We are doubling down on this commitment by working with our equity market employees as well as joint venture and licensed market partners in a concerted effort to welcome and seek opportunities for those fleeing war, violence, persecution and discrimination," he said.
Schultz said Starbucks would begin "by making the initial focus of our hiring efforts on those individuals who have served with US troops as interpreters and support personnel." (In sharing the letter, a company spokesman said Starbucks would not comment further on it.)
Schultz also reiterated the support the company expressed in a letter last week for "dreamers," or undocumented immigrants brought to the United States as children. He tried to reassure employees they would be able to return to the company's health benefits without waiting for open enrollment if the Affordable Care Act ends up being repealed.
And he detailed the company's relationship with Mexico, where it has 600 stores and sources coffee: "We stand ready to help and support our Mexican customers, partners and their families as they navigate what impact proposed trade sanctions, immigration restrictions and taxes might have on their business and their trust of Americans."
For many CEOs, a letter with such lofty rhetoric addressing political hot-button matters would be unusual, but not for Schultz. He has long been more willing than most CEOs of companies Starbucks' size to speak out on societal issues, fueling a brand identity carefully constructed around corporate responsibility and community mindedness.
In 2013, Schultz told an investor he could sell his shares if he didn't like the company's stance on same-sex marriage, and he has been credited for company programs that have offered college education benefits and hired young, minority workers and veterans. Other efforts have been panned, such as his "Race Together" campaign to get baristas and customers talking about race. Many saw it as tone deaf, an overreach in bringing political topics into a business transaction.
In March, Starbucks put together a series of online videos designed to teach lessons on civic engagement; he also spoke openly at Starbucks' annual meeting for investors about the lack of civility and leadership in the country.
"There are moments when I've had a hard time recognizing who we are and who we are becoming," Schultz told shareholders. "We are facing a test not only of our character but of our morality as a people."
As a result, he has repeatedly faced questions about whether he's interested in higher office. In an op-ed in the New York Times last August, Schultz said he has "no intention of entering the presidential fray," though in a September interview on CNN, he didn't entirely rule out a run. "I'm still a young man. Let's see what the future holds."
Later, Schultz added, "I determined for myself that at this time, I can do more as a private citizen and as the CEO of a public company to advance the causes that I think are important for the country and for our company."
In his letter Sunday, Schultz did not just express his own concerns; he also made a direct appeal to employees to get involved in the political process.
"If there is any lesson to be learned over the last year, it's that your voice and your vote matter more than ever. We are all obligated to ensure our elected officials hear from us individually and collectively," Schultz wrote. "Starbucks is doing its part; we need you to use the collective power of your voices to do the same while respecting the diverse viewpoints of the 90 million customers who visit our stores in more than 25,000 locations around the world."
He closed by trying to reassure employees.
"We are in business to inspire and nurture the human spirit, one person, one cup and one neighborhood at a time - whether that neighborhood is in a Red State or a Blue State; a Christian country or a Muslim country; a divided nation or a united nation," Schultz wrote. "That will not change. You have my word on that."
