i try to work through these problems internally whenever possible. you can tell someone that you're not always you, but from their perspective, when your physical body does something, you are responsible for it. even if you weren't you at the time. it can be very hard to understand from the outside looking in.
within my own system, if i have alters who are causing troubles at work, at home, with friend, etc., i try to work it out with them, rather than try to work it out with bosses, co-workers, wife, or friends. when done respectfully and open-mindedly, i find i get better results this way. it gives me a better platform to find out the root of the problem, and often paves the way to more insight from an alter.
i don't know how much co-consciousness you have, or how your internal communication works, so it may be different for you. just my suggestion.
