It is two decades since I learnt a very valuable lesson in human resources. The incident was painful and embarrassing, but remains hugely insightful even today.

I was attending an extended training session. I was sitting in a circle, amongst my colleagues, one of the more senior members of the team. My assistant complained that I had not listened to him on a certain issue. I answered back. He then proved to me that this had occurred several times previously. And on each occasion, there had been a negative fallout.

Punch line – said in front of everyone. “Michael you cannot keep ignoring all the time what somebody is warning you. And then once the mistake has happened, you blame somebody else.”

In other words, at what point in time was I prepared to take responsibility for my actions, and how I had trained my own unit?

I went home a lot of humble pie.

I have since move on to become a business coach and mentor, primarily in the Jerusalem area. I have frequently confronted by CEOs, determined to shift the focus of their troubles on to the shoulders of their employees. Showing these leaders how they can change and thus an impact a situation is one of my challenges and thrills of my work.

And all of these thoughts can flooding into my mind when yet again I was reading about Jeremy Corbyn, the leader of the Labour Part in Britain. Now, as somebody born and educated in London, UK politics still interests. And to observe the need for British Jewry in the year 2018 to demonstrate against the demonic rise of anti-semitism in the Labour Party is deeply concerning.

We know that Marxists have a fundamental problem with Judaism. They, including Corbyn, claim not hate Jews. However, the religion is also a nation, which emerged long before the modern Israel-Palestinian conflict. That is an anathema; complete no-go territory.

Has Corbyn been warned previously that his words and actions (or lack of) and those of his supporters are offensive, degrading and unacceptable? The answer is a categorical yes, as this link will testify.

How many times? According to Labour MP John Mann:

Seventy-four is the official figure but there is a very significant number of others that have not been properly registered. It is many more than 74. There are around 130 other cases I know of which have been put in. They are going to be resubmitted, and I am asking for them to be properly assessed. What is depressing is that there are so many cases being dealt with officially – and that it had taken so long to deal with them. We are talking the last two or three years.

So Corbyn has been told of the issue. And he has done nothing about it, or next to nothing. That makes him the root of the problem. As per the theory laid our above, he is the one that must change.

Maybe he can start by recognising that Jews pray to Zion, and that is located in Jerusalem. That could be so confrontational, that it might conjure up a painful shout of “oi vay”!

(Just as I finished writing this blog, it emerged that Corbyn has been a member of 5 virulently anti-Semitic Facebook groups).
