There’s nothing more infuriating than someone taking credit for your work. We’ve all had this happen at one point or another: you share an idea with a colleague and then hear him repeat it in a meeting; you stay late to finish a presentation yet your team member accepts all the praise; you lead a long overdue project to completion and your boss tells the higher-ups it was his doing. How should you handle these situations? Is it okay to speak up right then and there? Or should you keep quiet? And how can you make sure that you get the credit you deserve in the future?
