How do non-admin employees invite coworkers to join Workplace?
If your system admins have enabled it, anyone in your community can invite coworkers to join them on Workplace.
To add users individually, click Invite Coworkers from your News Feed. You can invite multiple coworkers by entering multiple email addresses.
If the users you're inviting are already on Workplace, an error message will let you know. If required information is missing, admins will receive a prompt.
Note: You can only invite coworkers to join Workplace if your admin has given you permission. Keep in mind that you can only invite people to join Workplace if they're employees of the same company.
