Hurt by Japan's devastating earthquake and tsunami, IT vendors NEC Corp <6701.T> and Fujitsu Ltd <6702.T> have decided to refrain from making personnel and organizational changes, previously scheduled for April 1, the Nikkei business daily reported.

NEC, which had planned to reassign about 8,000 employees, or a third of its workforce, will go through with promotions in April, but will postpone changes for about 6,000 workers until July, the paper said.

The company, one of Fujitsu's main rivals, suffered damage at five plants, including a key facility for telecommunications equipment in Fukushima Prefecture, the Nikkei said.

Fujitsu, Japan's largest IT vendor, also plans to postpone all such organizational changes, by a month. A unit of Fujitsu in Fukushima Prefecture was hit by the earthquake, and the company has not been able to resume full production of personal computers, the daily said.
