In a filing with the SEC, Cisco last night said it would reduce its global workforce "across all functions" by 6,500, including 2,100 who have elected to take early retirement.
This figure amounts to roughly nine per cent of Cisco's total worldwide employees.
Cisco employees will learn of their fate in early August. It is not yet known how many will be leaving the UK operation.
