Just another rant here. My last post mentioned the idiocy of finding work after fifty. Here describes work no matter the age.
It is very simple. It is not what you know, it's who you know. Unless you are one of the original employees, the first thing one finds when securing work is the good ol boy (good ol girl), network. If the other, older, in terms of seniority, employees like you and you 'fit it', you have a chance. But, if you are independent and also an outsider, which as a newbie, you will be, you don't stand the proverbial snowballs chance. You could be working in the tropics at a place that does not have A/C, and it will feel like the Arctic. You will be tolerated but only until a suitable replacement is found. You'll be treated as if you are trying to take their jobs. Iceberg shoulders and Icicle stares will accompany you all around the workplace.
You have three choices. Give in and become one of the masses and hope you can find a clique to fit into. If that is not to your liking, you can become a penquin and hope for the best. But your medically safest method is to find a different job. Eventually one opens up that actually accepts outsiders. They are rare and far between, but unless you can start your own company or are independently wealthy, those are the only choices.
Bear in mind that if you do manage to survive the working conditions, you still have to contend with management and you must realize that most management positions fall victim to the Peter Principle.
