01b00My Boss Question:02b02br
02br
01font00Is there anyone agree with you to work onsite other the normal working hours?02font02br
02br
01b00My Answer:02b02br
02br
01font00Actually nobody has instructed me to work onsite or offsite after normal working hours .I just took my own initiative to work around the clock and also on weekends to learn as much as possible and to produce deliverables above expectation by trying to achieve exact dateline on time. Even I tried to work till wee hours but I have not neglected my normally working hours. I am trying to push my ability to do more than my current job and by doing so, I am also making sure that I do not shrink my official job duties while taking on more.02font02br
02br
01font00Sometimes I think it is good for the top management to understand the subordinate's philosophy. I would like to share with you some of my personal philosophy…02font02br
02br
01font00I am working hard to broaden my horizons and to develop a host of skill sets that could be contributed to the organization and to the team for betterment.02font02br
02br
01font00To achieve great results, I think one has to change their mindsets01b00 from02b00 01font00“we work because we have to”02font00 01b00to02b00 01font00“we work because we want to”.02font02font02br
02br
01font00At the moment, work is not just a job to me, but it’s a hobby; a game; a business and its fun to work. With these we can go beyond the call of duty, take on added challenges and put in extra hours to achieve excellent results.02font02br
