If you don't spend 4 -5 hrs OFFICE time in Tea/lunch and Gossip. You don't need to work unpaid extra office hours. We Indians need to change our attitudes and stop thinking that MY BOSS will think I am doing more work as I stick around in the office for more hours even with 1% productivity in those 16hrs! Your Boss is enough matured and has gone through the same phase and knows what all do. I will say, if you are paid for a 9am to 5 pm job, stick your ass on the chair and DO the WORK dont just hang around and do the jobs for which people are already there just like ordering Tea, Printing NEWS article, FORWARDING the shit E-Mails to your girlfriends and family members. If you take out this time from your working schedule, you will know you are just using 2-3 hours to work out of the 16 hrs spent in office.
Please change the ATTITUDE and be sincere to work. I work from 9am-5:30pm in a much B2C performance driven job, then too my BOSS can't dare to say I should stay a minute after 5:30pm, cos he knows where my ass is when I am in the office from the Reports I produce and Money I bring into the business.
Hope this helps to all the WORMS who hang around in office wasting Nations Resources like ELECTRIC and Water.
