The extent of this cut has been mentioned within Rolls-Royce by senior managers, but it has not reached a final decision and there are many negotiations that need to be carried out, the source added.
Accordingly, these two companies will pay Rolls-Royce based on the duration of Rolls-Royce's engines.
The Financial Times had previously reported that Rolls-Royce is preparing to cut about 8,000 out of its 52,000 employees.
A final figure announcement will be made before the end of May when the company updates its personnel, according to a Financial Times report.
Last month, Rolls-Royce reduced its sales targets for this year and stopped paying dividends to strengthen finances, facing difficulties caused by the COVID-19 pandemic.
Warren East - CEO of Rolls-Royce said in April that the company will consider cutting cash spending, including salary costs for its global workforce by at least 10% this year.
The Financial Times also added that this personnel cut may be greater than the cut after the September 9 terrorist attack when the airline cut 5,000 employees at that time.
