Slack changes ticker symbol to WORK ahead of New York Stock Exchange debut

Slack is looking to complete a direct listing, rather than an IPO, on the New York Stock Exchange. Slack is gearing up for its stock market debut and has landed on a new ticker symbol: WORK. In an updated prospectus on Monday, the company said it's received approval from the New York Stock Exchange to list under that ticker after previously applying to list it shares under the symbol SK. It's a subtle but notable change in the run-up to one of the more widely anticipated technology offerings of 2019.
