Uber CEO Travis Kalanick is back under the scanner for inappropriate behaviour in an email written to his employees that has leaked and made its way to the Web. This email was written as a do’s and don’ts list for Uber employees heading to Miami in 2013 to celebrate a big milestone of the company. At that time, Uber had launched its service in the 50th global city and was taking 400 of its employees to Miami to celebrate the feat. The letter is said to have internally been called the ‘Miami letter’ and it contains explicit language including conditions on having sex with co-employees. This letter is now reportedly being scrutinised by two law firms as the company is under investigation for corporate misbehaviour.

The email is written in a rather boisterous manner with profanity used generously and has quotes like, “You better read this or I’ll kick your ass.” The email goes on to warn people to behave in Miami, and not do inappropriate things like drugs, vomit, and more.

Uber CEO Travis Kalanick's Letter to Employees Leaks, Contains Rules for Sex With Co-WorkersThere’s also a condition mentioned for having sex with employees, and in Travis’ words, “Do not have sex with another employee UNLESS a) you have asked that person for that privilege and they have responded with an emphatic “YES! I will have sex with you” AND b) the two (or more) of you do not work in the same chain of command. Yes, that means that Travis will be celibate on this trip. #CEOLife #FML.”

This is a classic depiction of the existing startup culture, and the bro language that is usually used in conversations of executives and employees. However, Recode reports that this email has become relevant again after the company is under investigation about corporate misbehaviour at Uber.

The report states that law firms Perkins Coie and Covington & Burling are looking at whether the letter “helped created the party atmosphere that led to the sexism and sexual harassment, as well as general corporate mismanagement.”
