Not making yourself indispensable
One of the biggest mistakes people make in their career in today’s layoff-prone world is not becoming truly indispensable. Find a task … your boss hates to do and offer to take it over. You might tell the boss you want to do it to gain the experience and to continue your career development, but that’s only part of it. If losing you will mean going back to doing something the boss hates, he or she will fight for you as if you were the company’s most valuable employee.Not maintaining your network
A common mistakes workers make is networking only when it’s of immediate value. Doing so can appear self-serving and may dissuade contacts from advocating for you.The best networking occurs when you don’t need something. This is when you can form genuine relationships with people and really learn about how you can help each other. The best networking is mutually beneficial. Besides, you don’t want to become who only reaches out when you need something.
Not increasing your marketability
Once you commit to a career path, you might think that the knowledge acquired at your job is enough to keep you marketable. In this competitive economy, that’s not always true. Find other ways to continue your education and sharpen your skills, so the next time you’re looking for a job, you have an edge.If your company offers tuition reimbursement, take classes that will enhance your résumé. You might consider getting a certification in your field, since certifications have become very common in many fields.
Being too humble
If you’re someone who puts yourself down — this is probably a stupid idea, but … — or downplays your contribution to a big client win — “I didn’t really do much; it was Paul who did most of the work” — stop it now. Sure, you don’t want to come across as pompous, but if you don’t make your achievements known, you may be passed over for promotions or high-profile projects.It’s up to the employee to position and communicate accomplishments and success, and to identify how they contribute to the success of the team, the department and the organisation.
