Twitter to start employee cull this week: Report

Days after his official reappointment as CEO at Twitter, Jack Dorsey is reportedly implementing his first reform this week, with departments company-wide set to undergo staff layoffs.

Twitter is reportedly planning to cull staff across multiple departments this week.

Insiders told the online publication Recode that whilst it is unknown how many staff will be let go, it will reportedly affect most departments within the social media giant, with engineers expected to be greatly impacted.

"We're not commenting on rumour and speculation," a spokesperson for Twitter told Recode.

Recode highlighted the staff-cull comes at the same time as Twitter's engineering organisation undergoes a restructure. With roughly 4,100 employees at present, engineers account for approximately half of its staff.

Recent restructuring at Twitter has not just affected its staff; management has also undergone a shakeup of late.

The San Francisco company officially re-appointed its co-founder Jack Dorsey as CEO, after an almost eight-year hiatus from the role, in which he was replaced in 2008 by fellow co-founder Evan Williams.

Dorsey was acting in the role since June, with his predecessor Dick Costolo stepping down as CEO, but remaining with the company as a member of the board.

"This transition is not the result of anything more than Dick deciding to move on from his role as CEO," Dorsey said at the time. "There is no connection with our near-term results as you can see from our reaffirming our long-term outlook."

Costolo first joined Twitter in 2009 as the company's chief operating officer, and was promoted to CEO in 2010. Last week, however, it was also announced that Costolo would step down from the board, effective immediately.

In a series of tweets last week, Dorsey said Twitter is "working hard" on strengthening the team.

Dorsey is also the CEO of payments service Square, with the Twitter chief hoping to run both postcode-sharing companies simultaneously.

"Both companies have strong businesses and are well positioned to grow their impact in the world. I will do whatever it takes to ensure that," Dorsey said.

Last month, Twitter and Square announced a partnership which saw the launch of a service that allows users to make donations to political campaigns directly from the Twitter app.
