Official working hours is 8.30 to 6. But most people arrive between 8.45 - 9.15, depending on your office culture. and usually people leave right on the dot at 6.

breaks are not officially given, so it still depends on your office's culture. I've seen people going for:

Breakfast from 9 to 10.
Lunch from 12 to 1330.
Tea break from 3.30 to 4.30.

There are many different kinds of leaves given, often organised events that promote family life. But there are many scholars in there.

you have to be really cautious with how to safekeep all the confidential documents well (not leaving them unattended), laptops issued should never be lost, and the way you handle emails also have to be well managed (you cannot send out things without thinking).

All in all, i believe dsta is a good place to work, people seems to be happy as shown on their face.
