female colleagues [...] quarreling take 2 hours for launch where they meet and talk [...] spoil the ones that are serious on their work [...] using officer computers to browse for dresses [...] giggled past the whole day
On the face of it, this sounds appalingly sexist,
however...
We are given specific responsibility as a small team (2 to 4) and there's no way of running from it.
...
However, the problem here might simply be small sample size. If you are saying the women in your team of 2 to 4 are a problem, then it seems likely the problem is the person/people, not the gender. If someone is performing below expected standards, but it's only one or two people, then gender doesn't really come into it. And so we shouldn't generalise.
I don't know if it's just my office or everywhere. Being a women should not give them a privilege while the male counterparts are working harder for the same pay grade.
Sounds like it's just your office. Where I work, the gender balance is pretty good, and I do believe gender doesn't even come into decisions about promotion, pay, etc. Plenty of directors and other high pay grades are female. And you know what? We have actually reached the stage where it doesn't matter and no-one even considers it. But this is certainly not the case everywhere... I've worked places in the past where women worked just as hard as the men, but were often paid at a lower rate, or unfairly overlooked for promotion. Thankfully as a society we are slowly reducing the imbalance.
