The CEO of Uber is apologizing to all eleven-thousand of his employees. Travis Kalanick tweeted an apology last night after a six-minute dashcam video was released that shows him throwing a tantrum at an Uber driver. The argument began after the driver complained that reduced fares were costing him money. Kalanick told him to "take responsibility," and complained that some people "blame everything in their life on everyone else." The video sparked outrage on Twitter, and threats of an Uber boycott. Kalanick responded by issuing an apology, saying, "I must fundamentally change as a leader and grow up." He added, "I need leadership help and I intend to get it."
