If the advice competes with the employer, it violates loyalty. Additional compensation is not an issue since a client of the firm is not offering compensation.
b)Depends, if his job as bartender would impair his duty as an analyst (I think the CFAI book mentioned an example of an analyst running for mayor of some town, the book states if the analyst has to devote substantial time that impair his duty, then he has to report).
c)Yes but not sure
d)Yes but not sure (even though nonmonetary and montary compensation are treated the same)
e)Again depends, reasoning is the same as b)
f) Refer to the post above, even if its free, if the advice competes with the employer, then he violated his duty.
My two cents, I hope somebody could shed some light on it too!
Thanks everyone for your inputs. The examples are provided by me. I think Garnopolis422 summarises this very well:
Loyalty to Employer : If activities compete or potentially compete with your employer and written approval is not obtained, then it is a violation regardless if compensated or not. And if any activities that does not compete but impairs duty to employer (eg. too much late night resulting in poor performance at work), this is also a violation.
Additional Compensation : Is only applicable to additional compensation related to work under employer and does not cover non-work related activites (Eg. receiving payment for being swim coach).
