I left school aged 15 having been told by my mathematics master that I was worthless. High school education was all I had

I worked hard and was always available to do whatever my employers reasonably required including be able to be contacted at any (again reasonable) time.

Before I left Australia in 2010 I was on a "Hollywood" salary which with my overseas earnings has set me up for life. Hard work has its rewards.

Anyone who is "offended" by being contacted out of hours is a flaccid organ.
