First and foremost, master and perform well in your CURRENT position! Sometimes we're focused on the next position, that we stop caring about the job we already have. If you don't do a great job now (no matter how bad the job is), why would you be promoted? Take an honest assessment of your performance, ask for feedback and become a rockstar! THEN, start looking for a promotion.
Work hard and diligently. Make yourself noticed. Don't be a pushover, when you've completed a project let your boss know what you did, how you did it and how much success you've met.
Act confidently. Approach your boss, and without being arrogant or pushy, explain why you are a perfect candidate for promotion.
If you get passed over, ask you boss what you need to improve on in order to get a promotion. Be confident!
When negotiating a salary, pay rise or promotion imagine you are doing it on someone else’s behalf. It’s amazing how coy even the most accomplished women get when asking for money.
Don’t become so invaluable in your position that you’re the only person who can do it.. groom juniors to take over your role once you have a new target for yourself in sight.
When negotiating, it's helpful to ask for slightly more than you're anticipating. Shoot for the top of the range that has already been indicated or discussed for your position, plus 10-20 percent for good measure. This way when negotiations begin, you leave yourself enough space for bargaining and still come out with your anticipated salary!
Also, don't forget to ask! You'll rarely get a promotion or a raise if you don't say what you want. Give your reasons for asking as well. Have some data or examples to demonstrate your worth. It's difficult, but necessary.
Get offered another job. Even if you’re happy in your job, every so often you should put yourself about a bit. Nothing makes you more attractive to your boss, than him knowing other people want you too. But be prepared to leave if they won’t give you a pay rise. You can’t cry wolf and get away with it.
Almost the most important thing is timing. Don’t do it when it suits you, do it when it suits your boss. Learn to read her moods. Don’t ask when she is frantically busy or in trouble herself. The best time is when things are going well and she is feeling happy and confident about the future of the company.
