3Com revealed it would cut its workforce by 30%, or 3,000 people, while NTL said it planned to increase the number of job cuts from the 1,300 predicted last year to more than 2,000 in an attempt to save £200m over the next two years.
3Com CEO Bruce Claflin said the move was designed to return the company to profitability. "Our cost-cutting efforts are more important than ever, given the softness we have seen in demand, both in past quarters as well as the current quarter," he said in a statement.
The job cuts, which come after February's announcement that it planned to axe 1,200 positions, will reduce 3Com's headcount from 10,000 to 7,000, but it remains unclear how many posts will go from the UK's 800-strong workforce.
Claflin added the cuts would be a major contributor to 3Com's efforts to return to profitability.
3Com was also evaluating the possibility of cutting property and plant expenses as well as reducing the cost of product designs.
NTL claimed its job losses were designed to reduce its cost base. The cable specialist has acquired 11 companies in the last 18 months, so the redundancies are expected to be spread over two years as it integrates the acquisitions.
NTL is not expected to return to profitability until 2004.
