"I can't imagine they'd let me go after all these years."
Yeah, that's what 1,800+ ex-employees thought in January 2018. They were axed because they were expensive. They were expensive because they were with the company 10,15,20 years or more. 2% increases per year, year after year. Your loyalty only means you're overpaid for your position.
"Our magazine sales have been down, but can't imagine the rest of them know the area like i do, at this point"
You're joking, right? It's a bunch of magazines in a row, not brain surgery. Literally, it would take one day to learn all the ins and outs you accumulated in 17 years. Pulling old magazines and replacing them with newer issues isn't NASA material. Besides, have you noticed how many periodicals are no longer being published? It's all digital and more magazines will cease publications this year. How do think that bodes for your newsstand?
"But, today, again, there i am, showing another kid how to zone my section, where to put returns, etc. The kid seemed uninterested so that might work in my favor."
This statement blows my mind. You are literally training your replacement and you know it. BN doesn't care about how uninterested the kid is, he makes less than half of what you do. That's what BN cares about. The only thing that is going to work in your favor is updating your resume and getting out there and find a better job. You posted on this site asking "Am I Safe?" and the resounding response has been NO! Yet, you seem determined to "ride it out". Don't. Seriously,don't be passive and let them demote and/ or lay you off. Please get control of your life and start looking for a new job. I know it is scary and hard to go out there in the job market after 17 years at one company, but you can do it. You're smart and you have valuable skill sets.There are so many resources and agencies that can help you for free. Many of us are have great jobs after our careers ended at BN. You can have a great post BN job also. I'll be thinking of you and wishing you all of the best as you start your new journey.
Even though this post by @YkltML1-2rzp was originally a reply to another thread and the post is a reply to another posters statements on that same thread, I found it to be a good representation of the sad condition that the company is in and the ill way in which things are done.
