The venomous women were supposedly the talented employees I had headhunted to achieve my utopian dream - a female- only company with happy, harmonious workers benefiting from an absence of men.
It was an idealistic vision swiftly shattered by the nightmare reality: constant bitchiness, surging hormones, unchecked emotion, attention-seeking and fashion rivalry so fierce it tore my staff apart.
When I read the other day that Sienna Miller had said there was no such thing as 'the Sisterhood', I knew what she meant.
I can understand why people want to believe that women look out for each other - because with men in power at work and in politics, it makes sense for us to stick together.
In fact, there was a time when I believed in the Sisterhood - but that was before women at war led to my emotional and financial ruin.
Until reality and a heavy dose of estrogen stopped by and burnt the place down.
