BBC reports: Blackberry manufacturer Research in Motion has said it is to cut 2,000 jobs as part of a shake-up of its operations.
The planned job cuts would account for 11% of the Canadian firm's workforce.
The firm also announced that its chief operating officer (COO) Don Morrison is planning to retire.
He will be replaced by Thorsten Heins, currently COO of products at the firm, who will take on an expanded role including products and sales.
The news comes after RIM announced in June that it had missed its lowered profit forecasts and reduced its predictions for the full year.
The company's share price has fallen by more than 50% since the start of the year.
RIM made a net profit of $695m (£430m) in the three months to 28 May, down from $769m in the same period last year.
It had warned in April that its profits would be low because of reduced shipments of its Blackberry phones.
Blackberry has been overtaken in the smartphone market by sales of phones running Apple and Google Android operating systems.
