Unfortunately, automatically adding cc users is not yet possible. However, I'll add this topic to the existing feature request for this.
As for a workaround which includes less manual work. But required more setup to get started. You could do this with a scheduled report alert, meaning:
Every day, this user gets a report with the ticket information of all new employees of that day. The frequency of the report can be adjusted if needed.
You can create a report which shows the tickets of the new employees and all the information the user needs, because scheduled report alerts will only send out an email if the report has a value, if no new employees have been processed that day, no report will be sent.
