That's how bosses tweetent – business

• When managers comment on Twitter and on other social media platforms, there is always a risk involved.
• Many bosses are cautious and mostly talk about their own business and their own accomplishments .
• Politics rarely flees the boss of Siemens Kaeser. Sometimes this can be difficult, as in a meeting with US President Trump.

When bosses tweet (there are only a few), there are very different schools. There are the announcers and the heralds. For example, Karl-Thomas Neumann, former VW man, former Continental manager, former boss of Opel. The man writes when he quits his Opel job ("just quit the board"), when he has a new job, or just like that ("I'm sailing with friends across the Atlantic.") Often this is Twitter is Karl-Thomas Neumann's entries to Karl-Thomas Neumann

Then there are the real professionals: Bill McDermott, CEO of SAP, does not just vigorously promote the products of his software company and his own biography entitled "The dreams of the winners", He also presents with Angela Merkel ("real personal honor to meet the Chancellor") or with Sebastian Kurz. He praises the African commitment of actress Charlize Theron – and for Mother's Day, he simply praises his "mom": "She was the force of sheer optimism, I owe her everything. Another, much smaller group of managers are tweeting to start the debate. Such a Twitterer speech is the CEO of Siemens, Joe Kaeser. It does not always write about digitization in China or on gas turbines. A few weeks ago, the head of the AFD, Alice Weidel, attacked the federal government's immigration and asylum policy in the Bundestag and spoke of "girls in the headscarf", "Cutlers" and "other goodies". the boss of the Munich tech company is no longer He tweeted in return. "Dear scarf girl as a group of German girls, Ms. Weidel's nationalism is damaging to our country's reputation in the world, where lies the main source of German prosperity." A Clear Statement

The 61-year-old from the Bavarian Forest gave journalists at Club Wirtschaftspresse Munich an unusual view of his political worlds – and explained why he returned despite Hard debate would respond to the AFD Ms. Weidel. "We can not leave the field free for populists," he said.

In May, many people came to Kaeser, most of them in social media ("That brought in at least 3,000 new followers"). There was much encouragement, the Archbishop of Canterbury contacted him. But many have also criticized Kaeser for his tweet. He was, according to Siemens boss, partly "very rough, really aggressive, violent" become. Not only was he then threatened, including his children and his mother: "The activism of the threats left a considerable impression." But he does not regret his statement. "I had the impression that you could not let that go," says Kaeser. Defend the beginnings, that is his motto.

Now he stands on a warm summer evening in the Munich courtyard with a glbad of water in his hand. He takes a longer break, then he says thoughtfully, "If everyone was forced – who were the authors?" His conclusion: "Anyone who makes a public statement today takes a huge risk." For the CEO of Siemens, it was even more delicate. But you just have to do it – even if it is not always easy.

Kaeser is often alone with his clear statements about politics

. There, he met with 14 other senior international officials in Davos with US President Donald Trump at a dinner and praised his tax policy. Trump later said that he has now won "15 new friends". "I thought, I really do not do it," Kaeser said today. You can understand that anyway. In any case, even Kaeser says, "We get on well with the United States." Until now, no Trump tweet has been 'negatively mentioned'.

In general, the economy, politics and the subject of responsibility: he quotes the clbadic "politics as profession" of Max Weber – unusual for the boss of a Dax. Group: "Politics means slow, solid drilling of hardboards with pbadion and judgment at the same time." For example, on the subject of refugee policy, where Germany has "the laugh of the world" on itself. Kaeser, as a committed domestic politician: "Without an immigration law, we will not regain control."

Kaeser often stands alone with his clear statements about politics. He told his colleagues to do something together, he said. But hardly anyone wanted to get involved. Even 16% of AfD voters are just customers. He does not want to name any industry, but some people seem to fear that fewer cars or sneakers will be sold. Kaeser adds, "I do not have a problem with gas turbines." Remain a question: will there be politician Kaeser after this evening? Siemens boss response: "I do not know if I could."
