Long-time "older" employee.
I think I am in the minority in that I figure this is just the way things are.
There is no such thing as job security these days.
It's only business and not personal.
I hated being let go.
Everything that was comfortable was taken from me, but ultimately I am just a number and that is the reality most places you go.
Keep your Linkedin up to date, keep yourself open to recruiters on Linkedin.
Always be ready your next move.
Long gone are the days when people stay at companies for years on end.
Before I found my current job, I had more than one recruiter tell me this.
