Twitter has announced it's letting 336 staff go.
It says it's made some tough but necessary decisions to be able to grow.
It's not known if any of its Dublin staff are affected.
A memo to staff from the company's CEO reads "We are moving forward with a restructuring of our workforce so we can put our company on a stronger path to grow."
"So we have made an extremely tough decision: we plan to part ways with up to 336 people from across the company."
"We are doing this with the utmost respect for each and every person. Twitter will go to great lengths to take care of each individual by providing generous exit packages and help finding a new job."
