Those are not appointments MC....they are internal promotions.
To me MC this is becoming petty. I do not think honestly we should go that low. Many organisations having been undertaking this kind of promotions either due to reorganisation or restructuring. Organisations ahve a free hand to do so unless you convince there were more qualified and deserving individuals who missed the oppotunity.
Soon you will be talking how a support staff from this tribe has been promoted and so on.
They are better ways of flaring tribal animosity; definitely this not being one of them.
