I'm currently in a part-time job at a mid-size company. It is a professional position despite being part-time, and I took it for the experience (I'm in the early stages of my career) and the promise of possibly being promoted to full-time, but after a year I'm finding it to be dissatisfying.
The organization is poorly run, my supervisor is ineffectual, and it appears that there will never be enough in the budget for our area to ever promote me. Plus my supervisor is not really capable of advocating for me, even though I do think he's a nice guy. And yet the workload is ever-expanding and I am taking on more and more responsibility.
I've been using my extra time to do small freelance projects, take professional development courses, and do improvement projects for our area. I think I'm doing a pretty good job maxing out the potential of this role.
My question is, is a year too short a time period to consider leaving? Will it be frowned upon by other employers? Or, better yet, will the experience be considered insubstantial?
Should I wait? I've read that 18 months is the minimum. Is there any merit to this? Because I'm ready to leave for greener pastures.
