Accommodating is the opposite of competing. People with an accommodating conflict style will diplomatically defer their needs to find resolution. They are not assertive and will sacrifice their desires for the benefit of the group or partnership. They are concerned about preserving their relationshps.
This conflict style is particularly useful when you don't care about the outcome of a dispue and want to preserve or build a resolution. For instance, if you'd prefer your partner doesn't invite someone to your party but it means a lot to them and not much to you, simply accommodating their desire could go a long way to show you care.
While this conflict style might seem generous, it can quickly devolve into being stepped on and building a pattern of submitting yourself to the desires of more dominant personalities. This can be especially problematic if you find yourself accommodating to desires that the other party does not particularly prioritize. You will build resentments that could have been avoided through some conflict and healthy assertion of your needs. If you often feel you are a martyr, you will eventually see others as brutes.
