A strong professional network can be an immense help in a professional career, but you must recognize that there is a thin line that, when crossed, can bring you many inconveniences. With that being said, here’s a list of things that you should never say at work:

1. “I hate my job”

Complaints are the worst references people can give about themselves and their jobs. If you do, you will surely be labeled as a negative person and you do not like to work as a team. As an aside, here’s a hilarious commercial illustrating this.

2. Pointing out others incompetencies.

There will always be people who are lazy, don’ do their job successfully or do things halfway. But if you don’t have the power to fire  them, then you have nothing to gain by issuing that judgment, for you’ll only be bringing attention to yourself and inviting additional scrutiny on your own performance. Your insensitivity may turn against you.

3. “I earn X money”

Maybe you can tell your close friends or family, but this is a no-no at work. It’s a way of comparing yourself with your colleagues.

And as soon as you announce how much you earn, many will judge your work in relation to your salary. Even once you know how much your teammates win and vice versa, you will most certainly will not see each other in the same way.
