Staff at mobile phone group Orange are braced for job cuts after the firm said it would reduce its workforce.
Orange is trying to boost its non-voice-related mobile services
While Orange said it is to cut a "small number" of staff, reports suggested up to 300 staff across its network and technical systems departments could go.
"These are only proposals at the moment and are not related to call centres or other customer-facing roles," an Orange spokesman added.
No locations have been earmarked for the redundancies, he added.
The move is part of a new strategy set out a year ago by former chief executive Sol Trujillo.
The Bristol-based company is hoping the proposals will make its products more user-friendly and also to boost the usage of its non-voice-related mobile phone services.
French state-owned telecommunications group France Telecom owns Orange, which has operations in 19 countries worldwide.
