About 3 months ago I accepted a new position in my company in a different department. A career change in a way. My company and department specifically had hit a rough patch. At the time of me accepting my new position a new manager was brought in to fix the issues within my department and to directly oversee me and my two coworkers. I spent a few weeks working under this manager before leaving for my new position and enjoyed the support I had begun to recieve making the job bearable again. I had become unsure about leaving after meeting with this manager but I told myself I was making a good move to advance myself.
In my new position I began to learn a new skill, see a new side of the company, and the amount of over time I put in has decreased drastically. However, I'm worried that this job will not be enough for me now that I've spent a few months there. In my old position I was at the front end of things, in a quick paced environment. I honestly felt more important in my previous position but I do not want to sabotage myself in this new position as well.
I'm unsure if this change has made me realize where I want to be within this company and department I want to grow in. That I let my frustrations get the best of me during a transition period and I could have been apart of the changes to come. Maybe I'm just having a hard time getting used to the new job.
While it is actually not uncommon in my company for people to move back to old departments I feel embarrassed and guilty now if I bring my concerns to someone. My leaving has been hard on my two coworkers who have now been down a person and it caught most off guard because I did not speak up about my frustrations.
Is it ok to bring these concerns up to a manager or my HR person? I'm worried to look unreliable but I was told before leaving my old position and during my review if I do not speak up I can not be helped.
