The Wall Street Journal reports that Troy Jones, director of Tesla’s North American sales, is leaving after 15 years at the company. This comes after Tesla reported a steep drop in sales for the second quarter. Other execs have similarly been fleeing. Elon Musk fired Omead Afshar, who formerly led operations in North America and Europe. And the company’s director of human resources for North America, Jenna Ferrua, departed in June, according to the Journal. The C-suite is getting thin.
