Of Unions and strikes

So Kenya Airways employees have been watching South African news and seem to have learnt a thing or two on how to go on strike. Reminds me of a joke I heard on one of the South African Radio Stations during the Confederations Cup. A presenter asked what were the chances of Bafana bafana (I wonder why the cant change that name which literary means Boys boys) winning the tournament. One listener called in and claimed the chances were very high that they would win, to which the presenter asked why he made that assertions. The listener quickly answered "because South Africa has very many strikers - Doctors, Teachers, Municipal Workers, Construction Workers, Taxi Drivers etc".
Kenya Airways just added to the number of strikers in Kenya - if only that could some goals to the scoreline of our beloved/obsolete Harambee Stars!
The one thing that I could not fathom during the 3 day strike was, how does anyone in their right mind demand a 130% pay increment for 3000 employees from a company that is recording losses? Do the union officials ever pose to do the maths? If the company gave such a pay increase, it would literary shut down in a few months and then what would become of the unionisable employees? They would simply add to the statistics of unemployed Kenyans.
I am not however claiming I condone the practice of underpaying workers, no, just that I find unions rather unreasonable in most instances and I am glad I have not had the chance to be in any union (apart from the marital union with my wife - but that is a different sort).
Secondly, we get the news they have reached a "back-to-work formula". And the agreement is....drumrolls....20% pay rise staggered over 2 years. The union demands 130% payrise, the management offers 20% (over 2 years) and everybody is happy???? Am I missing something here or was the "1" in 130% a Uhuru Kenyatta kind of typo?
Anyway, I am glad they are back to work as I was personally grossly affected by the strike and I hope the management learns how to read the moods of the employees/union better and know what to safely dismiss and what needs serious considerations.
