When To Write Effective Complaints

Writing when you feel as angry as "The Hulk" is probably not a good idea. It might be good to jot down major points of how you feel to jog your memory later, but as a general rule, waiting 24 hours from the time of your injustice is a good "cool down period".
When you return, try to view the situation as third-party or "outsider" would, then script a narrative in your letter that concisely conveys your message and shows what your expectations were, and exactly where the company failed to meet them.
Tips To Help Cool Down:
- Take a Walk.
- Have a Cold Shower.
- Meditate.
- Get a Good Night's Sleep.
- Take Deep Breaths.
- Listen To Music.
- Whatever it Takes for you to Temporarily "De-stress".
