You want to be successful. Everyone does. But your actual words might be undermining your chances of success. The things you say in the office, no matter how innocuous they seem to you, might be knocking you down the career ladder and putting the top position you dream about out of reach.Your career is too important to be tanked by a few negative phrases. Here are the seven things you should strike from your workplace vocabulary if you want to achieve the success you richly deserve:1. “That’s not in my job description.”When you accepted your current position, you had a good idea of what the responsibilities and workload of the role would entail. Throughout the months or years since you settled into your job, however, your role has expanded and changed shape. Some of these changes have probably been good, while others have made you wish for simpler times. When a boss or manager piles another responsibility on your already sore shoulders, it might be tempting to pull out this classic gem of work avoidance.The better option, however, is to schedule a time to talk to your boss about your role. A specific conversation about your place in the organization is a good time to bring up the particulars of your job description, not when you’re asked to get something accomplished.
