I prefer to work intensively for eight hours with complete focus, then leave relax in the evenings - work hard, play hard. My colleagues on the other hand, prefer to be in the office for 10-12 hours of the day, but spend a lot of their time goofing off - trading funny pictures via chat, telling jokes, etc.
We get the same amount of work done, but have very different attitudes towards it, neither of which are better or worse. But, it does make me feel very uncomfortable sometimes, when I am intensively focussed on something, and the rest of the office is lounging around chatting.
If I try and change my attitude to fit in with everyone else, then I would either have to work longer hours, or get less work done. I'm not going to work longer hours, because I really value my time outside the office, but doing less work grates against my sense of professionalism.
So I can either keep working intensively, and continue feeling like an outsider because I am excluding myself from the social activites of the rest of the office. Or I can relax, fit in with the rest of them, and instead sacrifice my professional integrity by doing less work than they are paying me for.
It all feels very awkward, and I really have no idea what to do. I wonder if there's a third option I missed?
