when i worked with the semi-government company, my working day was 7 hours without lunch break, 7:30 to 2:30(you could have some snacks, coffee, tea, etc. during the day at the office), with 2 days off. Around 2:15-2:20 the ladies used to start gathering at the exit area, ready to leave, but still discussing whose wasta is stronger and whose abaya is more expensive...by 2:29 you could only see the trains of their abaya's.. :) Men were following them very soon, although trying to behave with dignity and not push each other at the exit. By 2:31 the office looked completely dead.
Now, when I work for my hub's Company, I don't know my working hours, as I work as soon as I wake up until I fall asleep; I don't differ working days from weekends; I don't know what vacation is, as no 1 vacation day passes without opening both my Outlook and my Company folder in my comp, or answering business phone calls..
so here you go.. depends on who your boss is :):)
