Intel is reportedly planning to lay off 20% of its factory workers amid faltering demand for its core products.

Next month’s layoffs will take place at Intel sites around the world but could have an especially big effect in Oregon.

Intel laid off 15,000 workers last year and is preparing for another round of cuts next month, OregonLive reports, citing an internal memo. Intel Foundry head Naga Chandrasekaran informed employees about the job cuts on Saturday.
