If you feel your employer has treated you unfairly, it is important to realize that you may have legal options available when they have broken the law.
It is equally important to realize that telling everyone about your complaints may hinder your ability to get the situation resolved in a way that serves your best interests.
No one likes to be made to look bad in front of others
Your employer has likely worked hard to build up their business. Having an employee air their grievances about them in public could harm their reputation and undo a lot of the hard work they put in. Discovering you complaining to others could make them less amenable to resolving things in your favor. It might even cause them to dig in and go on the offensive against you.
An employer might not realize what has happened
Some employers are aware of what they are doing when they omit to pay the correct amount of overtime, discriminate against an employee and other such things. Others are not. Maybe an underpayment was just a clerical oversight or a miscalculation by someone in the accounting department. Maybe there is a valid reason for a decision you thought was down to discrimination. Or perhaps the boss did not realize one of his managers was letting their personal biases influence their treatment of employees.
Airing your grievances to work colleagues, customers or on social media could potentially create problems for your case. Not only could your words be used against you if there’s a dispute, but the public exposure may make your employer less willing to work toward a resolution. It is often better to mention problems to them first, to give them a chance to resolve them. If that does not work, you might want to seek legal guidance to bring more weight to the situation.
Going public with your concerns might also put you in breach of something you signed such as a non-disclosure agreement. Learning more about the legalities that affect your situation can help you improve your case while avoiding jeopardizing it.
