BlackBerry Ltd is cutting 200 jobs at its hometown headquarters in Ontario and in Florida in order to trim costs, it said on Friday, as the smartphone maker moves to turn around its fortunes and put more emphasis on its enterprise software business. “As BlackBerry continues to execute its turnaround plan, we remain focused on driving efficiencies across our global workforce,” the company said in an emailed statement. The layoffs will affect 75 manufacturing jobs in Sunrise, Florida, a state government website showed.
