Twitter emailed employees to confirm that layoffs will be made company-wide from Friday.

CTOnews.com, Nov. 4 (Reuters)-in an email sent to employees on Thursday, Twitter confirmed that company-wide layoffs will begin on Friday, local time, and employees will receive email notification of dismissal by 9: 00 a.m. local time.

Twitter will cut jobs by nearly 50%, according to insider sources and an investor, although the final figure has not yet been confirmed.

Twitter said in an email that the layoffs are designed to put the company on a healthy path. Twitter also said its office would be temporarily closed and all badges would be suspended to "help ensure the security of every employee, Twitter system and customer data".
