Arming yourself with the right information is a great way to boost your confidence and ensure you get treated fairly.
For example, by focusing on facts such as quoting a section of an Act (a statistic, credible report and/or result) is going to get you a lot more attention than focusing on a truth about a matter. Whilst there is absolutely nothing wrong with a truth, the downfall is that they are raw and emotional, which leave you vulnerable to others perception of your truth. By sticking to cold hard facts, you are less likely to draw too much emotion and allow you to focus on the real issue at hand.
To give a real life example, employee x got fired for pushing his luck with the boss (truth) or employee x got fired for breaching section x of the Fair Work Act (fact).
Now I’m not suggesting be a robot, but once armed with information, know when to pick your moments and when to use a fact over a truth and allow your confidence to shine!
