Dr Jonathan Deacon, from the University of Wales, Newport, says the loss of jobs in Port Talbot and Llanwern will be especially damaging to the local economies.
"These are the high-quality, white collar worker posts. The management posts, the admin posts tend to be the higher-paid and tend to be also where the knowledge is in the organisation"
"To lose those jobs out of an area like Port Talbot - which is not especially blessed with the ability for those types of workers to find other employment - it's going to be really hard."
"The knock-on effect is going to be felt in the local communities because of the economic value that those jobs bring.... where those salaries are being spent - new cars, holidays etc."
