One of the stressors that can get the person down is the pent-up feeling.
The intention of keeping quiet may be noble , that is to avoid hurting one's feelings but the tension or the damage that it creates to oneself may lead one's self-destruction.
When I an faced with this predicament, I try to look for someone who can do the talking for me; a neutral party. if it still does not work, I will do something to keep distance or possible get away from the people in order to avoid further aggravation.
It is different when a person is the introvert type who can not even talk to the boss to ask for a raise.
If she deserves to get the raise, one should build the confidence by preparing for the planned talk with the boss.
It helps a lot to prepare mentally and physically for this particular moment when the future is uncertain as to the reaction and decision of the top management.
