Hundreds of staff at telecoms giant Nortel have been laid off with many receiving no redundancy pay.
Nortel Networks UK, based in Maidenhead, went into administration in January after its parent firm filed for US bankruptcy protection.
The 1,200 staff were told on Monday that the job cuts were effective immediately.
“We can confirm 228 posts are going in the UK, but we can’t break the numbers down any further,” a spokeswoman said.
She added that administrators for the UK operations, Ernst and Young, would be on site to help HR staff complete paperwork for former employees to receive statutory redundancy pay from the government.
