Happened to me after 5 years of working there - one of the minions Legere's inner circle didn't like me. I've been getting calls every week as others tell me of their layoff. Severance was actually better than I would have expected.
S—s getting laid off, but it is what it is. Met lots of great people at T-Mobile, but also experienced perhaps the most toxic culture I have experienced in my career. Legere seems to be a genuinely decent dude - but I don't think his demeanor is the best for the people he has under him. Let's just say the talent at the SVP/VP level is underwhelming in their leadership skills.
