Twitter staff in the UK who face losing their jobs have been given three days to nominate someone to represent them in a formal consultation about their employment.
Under UK employment law a consultation has to be carried out before redundancies can be made.
An email seen by the BBC from Twitter's European HR department says they have until 0900 Tuesday to decide who to put forward, and was sent on Friday night.
Staff can nominate themselves.
If there are more than 10 nominations, an election will be held, the email said, although there were no details offered as to how this would be organised.
It comes after Elon Musk, the company's new owner, said he had "no choice" but to cut 50% of Twitter's staff worldwide.
Mr Musk said the firm he bought for $44bn at the end of October is currently losing around $4m per day.
The first Twitter layoffs were announced one day after Mr Musk bought the company.
CEO Parag Agrawal was among the workers who received their notice, with around half of Twitter's 7,500 staff expected to be cut.
Following the announcement, the workers union Prospect said it now has "dozens" of Twitter UK staff members on its books.
If more than 100 people in the UK are affected by a firm's job cuts then there must be a 45-day consultation before any redundancies can be made, it added.
