One might think (wrongly, I feel) that adjusting oneself to staff and conduct of a new workplace would necessitate quite a bit of time and effort, keeping one's head down and trying to fit in. As is common for me on most points, I demur. My preferred method of workplace adjustment and alignment is to get stonkingly drunk at the Christmas party, tell your boss dirty jokes while teasing him for hiring a complete waster (ie. me), dance like a mad thing and tell your co-workers (known for only four days mind) that you love them, and finally, round off the evening by snogging someone from another branch. Worked like a charm for me!
Everyone knows my name now (though 'the-new-one-who-got-off-with-John' is a bit of a mouthful) and there is no need to gradually reveal my annoying weird side, as it has been fully outed! Result!
