Constable & Robinson staff will move in to the Little, Brown office later this month.
Staff at the formerly independent publisher, which was bought by Little, Brown in February, have been undergoing a consultation on just over 20 roles in the business.
The consultation period has now been completed, but the “process is ongoing”, said Hachette communications director Clare Harington.
The roles involved are understood to be mainly in sales, marketing and production. Constable & Robinson currently employs 41 people.
When the consultation was announced, Hachette said it would do its “utmost” to find an alternative within Little, Brown or Hachette to any jobs made redundant at Constable & Robinson.
Constable & Robinson will move in to Little, Brown’s office on Victoria Embankment on 22nd April.
