Uber has reportedly laid off 400 employees from its global marketing team. The layoff is a part of organization’s effort to slash costs and make operations more efficient following its public debut and first quarter losses of $1 Bn.

About as much as 400 employees from the marketing team across 75 offices globally were asked to leave. Uber’s latest public global headcount was 24,494 global employees as of March 31, 2019.

According to a media report, Jill Hazel baker, who leads marketing and public affairs at Uber, and CEO Dara Khosrowshahi told employees Monday that the marketing team would have a more centralized structure.

The reorganized marketing team will be under the leadership of Mike Strickman, Vice President of performance marketing. Strickman will oversee performance marketing, CRM and analytics, while the global marketing executive will manage the heads of product marketing, brand, Eats, B2B, research, planning and creative.

Dara Khosrowshahi, Chief Executive Officer of Uber said the restructuring aims to put the marketing team, and the company, back on track.

Uber’s first quarterly earnings report as a publicly traded company gave a snapshot of a growing business with stunning operational losses. Uber’s revenue grew 20%, to $3.1 billion, compared to $2.5 billion in the same period last year. And its gross bookings rose 34%, to $14.6 billion, in the first quarter, with Uber Eats driving much of that growth. But its loss from operations exploded 116%, to $1 billion, in the first quarter compared to the same year-ago period.
