I am 67 and was at my previous for job 8 years. With new younger coworkers, one was clearly trying to push me out, while she was interning and learning to get ahead while belittling me.
I finally couldn't take anymore of this nonsense and the only thing management said was try to get along. Well ....here I am in early retirement..i was "Grandfathered " in so I found out most employers would rather take the younger. College grads.
Now I am trying to enjoy this time but my husband has 4 more yrs. Before he retires and he works second shift!
Wish me luck it sure is a lonely place to be.
