What I've learned is that, for employees, job security is never real. There is only silent risk. You might get lucky and go through an entire career never losing Russian roulette...but you're just lucky.
But I've also learned that there is no security of any kind in life. People who've lived nothing but peaceful lives will never understand, and they'll even lecture you about "making your own luck," when they should be thanking God for their good fortune.
