It's the company culture. Accenture's culture is either you go up (by raising your profile with the managers) or get lost. Their turnover rate is very very high and they don't care if people worked there 5,6,10 years leaving, they will bring 10 fresh grads next day, low paying, why not!?!

Not everyone wants to be workaholic, but being a responsible person, your project is due next week, will you work this weekend or not?

Accenture's culture is being pushy, getting projects with ridiculous deadline so that they get the deal and sales is boosted.
