Before using anything.
WHY IT MATTERS
Many organisations have a policy. Some prohibit particular tools entirely.
Using an unapproved tool with company information may be a disciplinary matter.
WHAT TO FIND OUT
Which tools are approved What may be sent to them What must be reviewed Whether use must be disclosed
IF THERE IS NO POLICY
Ask. That question is reasonable and it protects you.
WHAT IS USUALLY SAFE
Drafting your own communications Explaining something for your own understanding Structuring your own thinking
WHAT USUALLY REQUIRES CARE
Anything containing company information Anything containing customer or colleague data Anything going to a customer
WHAT IS USUALLY PROHIBITED
Confidential material Personal data Credentials Unreleased information
WHAT NOT TO DO
Assume it is fine because nobody said otherwise.
