If you got promoted, what do you think your colleagues would think? Do you think they would be happy for you or pissed off. Do you think that would motivate them, seeing one of their own moving up, or make them want to leave, ‘why has that guy got promoted over me?’
What type of tactics do you want to employ? Who do you want to be? What culture do you want in your organisation?
The answer to these is it does not really matter as long as you are happy with yourself. If you want to win at all costs, then probably no one will remember how you got there after a while and you will still have the title to show for it. You will be able to post-rationalise that that’s what it takes to be the greatest, or some other rhetoric. But you will remember. And so will the people around you at the time. Plus, just because you got what you think you wanted does not mean you will be happy with the result or the journey on the way there.
But there is another route. A route of really caring for others. A route of lifting other up along with you. A route of widening the “old boys club” to be more inclusive. A route of self-awareness rather than simply cutting out those who disagree with you.
Both work. One might take longer than the other. But which are you going to enjoy more in the long run?
