Nearly 400 jobs could be lost as UK telecoms firm TalkTalk attempts to "simplify" its infrastructure and operations.
The plans include the closure of a call centre in Northampton in England, but may also lead to the creation of new posts in other areas of the country.
Staff in Preston and Warrington, as well as those in Northampton, will be affected by the proposed changes and collective consultations on job losses are set to begin.
The company said: "There will be significant new opportunities for existing employees at Preston, Stornoway and Warrington and TalkTalk will be working with affected employees to maximise opportunities to transfer to new roles and thereby minimise job losses in a year that, ultimately, will see more UK roles created than lost."
It added: "It is proposed the Northampton site will close after the restructuring is complete with approximately 200 new roles created at Preston through the appointment of a new strategic partner to manage the existing site and some of its operations."
TalkTalk has also announced plans to create 250 engineering jobs later this year.
