4 Ways to Be More Assertive at Work
Confidence and assertiveness don't come naturally to everyone, but if you tend to be timid or reserved in work situations, those qualities could end up hurting you. Not only might an excess of mildness give others the opportunity to take advantage of you, but by failing to appear self-assured, you could ruin your chances at getting otherwise well-deserved promotions. That's why it pays to work on becoming more assertive -- and here's how.
Being humble generally isn't a bad thing, but when you apologize in workplace situations where an "I'm sorry" is by no means warranted, you discredit your own ideas and highlight your insecurities. Next time you disagree with someone or want to suggest doing things differently, don't preface your statements with "I'm sorry." Just say what you want to say, let your audience react, and respond as necessary.
