The owners let her "do her own thing" over at the branch location even though it she isn't experienced in the retail business and knows very little of our specialized trade. Now that she's back at the main location with us it's been horrible. The owners left it up to me to train her because I ran that location successfully for many years. I tried showing her the ropes but she doesn't follow through. I do all the cleaning and maintenance for the building while she sits in her office with nothing to do except play around on the company computer. The last time I asked her to help out she rolled her eyes at me! Plus, she chooses to isolate herself so we can't even get to know her.
I'm at my wits end! I want to scream and cry and quit. (I've already started looking for another job.) A newbie gets hired - shes one year younger than me - has no experience in this field and walks in and gets paid the same as I do! (Yes, I blame the owners just as much because she's not getting paid what she is clearly worth.) I've been with this company for 13 years now and crawled my way to the top. I attempted to talk to the owners about all of us not being on the same page. (You'd figure us working in a really small business they would have noticed that she is getting paid to do nothing?) I've tried having a heart-to-heart with the new woman to no avail.
Do I pull back? (Obviously, you can get paid the same for doing less.)
Am I being pushed out?
How do I handle her?
Do I just put my head down and find another job?
Sure, it's all OK for you to be a hard worker and basically work yourself to the top but you need to understand that not all people share your work ethic and it should be all about if you're happy and content where you are. Your passion for this business shines between the lines of your post but if you feel that the owners actions undervalue you and your commitment to them and their business, then you need to use your substantial 13 years experience to look for another position where you feel you will be valued and respected more.
It's never really about the money when it comes to your career, rather, it's about whether your contribution and value to the business/company is appreciated and respected regardless of long you've been there.
Keep your business head on. Write an objective evaluation of this person's training experience and what you perceive she brings to the company. List her good qualities and her challenges. If you can do this in a mature, constructive way, then the owners might see that you have a good vision of what the company needs.
That's all you can do.
If they don't appreciate your experience and 13 years of devotion to the company, get another job where people recognize your contribution.
