Different requirements, Different wages

In your post this is the bit that would tell me which job you should do

There is a car part company near me(yes you know which one) which all the agencies are going nuts trying to recruit for them(just recruit as you will carry the key to open their store so understandable they want full timers) and I heard they are really struggling to get drivers to drive their new scanias

If the car part company was any good drivers would be banging on the door to work for them.

Stay where you are
