Many of the women I talk to who feel powerless at work are actually giving away their power willingly. We often think that we "can't" ask for what we want at work. We believe we'll be denied and fired. But this fear is exactly what keeps us from getting what we want. After all, if you don't try to go for it, you will surely fail.
Instead, you can reclaim your power by actually trying to get what you want from your job (and yes, this works even if your employer is yourself). This is integral for you to feel your sense of personal power.
Ask yourself, what am I yearning for more than anything at my job? Get clear on the one thing that would make you happier now.
There are many ways to get what you want: getting a raise, asking for more time off (even if unpaid), volunteering for an additional project to build your skills, or even (gasp!) quitting.
But for now, I want to leave you with a simple step: imagine what it would feel like to have your wish to be granted. Imagine yourself getting a call saying your wish was approved. Where are you? What are you wearing? Who is with you?
For example, before I quit my last job, I imagined the relief I would feel after I quit. I imagined myself telling my husband I quit, and the hug he would give me. I imagined him telling him he's proud of me.
The first step to reclaiming your power at work is simply to remember that you are a powerful woman with powerful desires, and that those desires can be granted. Your imagination and visioning is integral to that reclaiming.
Before you create your strategy for asking for what you want, remember to sit with your desire, and to imagine the outcome.
