There is a very basic moral principle in life when dealing with grievances with others – the Mallet Rule. The Mallet Rule says that for every grievance that you have with another there is a proverbial toolbox at your disposal with mallets ranging from very small all the way up through hammers to a large sledge hammer.
Whenever you have a concern with another, you have a moral obligation to use the smallest mallet needed to get results, using the most polite, discreet and considerate means possible to effectively address your grievance. After having done this, if the problem is not corrected, you should escalate to a larger mallet but only one just large enough needed to bring attention to the problem, and so on until you find the right size mallet needed for the job. The Mallet Rule says that it is unethical to ever use a larger mallet than what is needed, to cause potential damage to relationships and reputations when it is out of proportion to the force needed to resolve the problem.
The Mallet Rule is an extension of the Golden Rule: do not do unto others what you would not want done to you.
