AlHijjah 29, 1436, Oct 13, 2015, SPA -- Twitter Incorporated said Tuesday it would cut up to 336 employees, or about 8 percent of its global workforce, as part of a plan to streamline operations. The layoffs, mainly in the company's product and engineering functions, come about a week after the microblogging service provider appointed co-founder Jack Dorsey its permanent chief executive. "We feel strongly that engineering will move much faster with a smaller and nimbler team, while remaining the biggest percentage of our workforce," Dorsey said in a letter to employees. "The rest of the organization will be streamlined, in parallel."
