If you are going to do something, take ownership, and do it right. If you do not want to do something, do not do it. Own your decision, either way, you choose. To not be in control of yourself, you usually will end up in the act of passive-aggression, and at that point, no one wins or gets what they want.
If you are a person who tends to be passive-aggressive, you are not treating yourself very well. You are volunteering for what you hate, just to please others, or you are letting others push you into actions in which you want no part. Either way, you are unable to give an honest attempt to complete the task with a decisive victory.
If you become forced into a position that may become passive-aggressive, would it not be better to recuse yourself and let the task owner find someone who could do a better job? While doing this, you are showing a better understanding of yourself, and others are seeing that you are a person of good stature who knows themselves and will not let others push work on them just because they are easy marks.
If you are giving jobs to people and you have someone who is often passive-aggressive, would it not be useful to hand essential tasks to others that would possibly cause fewer problems? Do not shut the passive-aggressive person entirely out of the loop. Instead, work with the employee to find out what their real skills and passions are. Give them jobs that relate to those skills and passions and encourage them. You may just find an outstanding employee that you never knew you had.
Thank you for being with me today. I hope to be with you tomorrow.
