On my first day at a new job I got given a sticker with my name on that I stuck to the lapel of my jacket. There were a few of us at an induction by HR.
I then took a car journey from the head office to the office I'd be working in. I was then introduced to all the people in the team I'd be working with (about 30 people) and I was shown around the lab. Somewhere along the way I'd lost my name sticker.
After the introductions I went to the toilet and found my name sticker stuck to the flies of my trousers. It must have come off my jacket when I had the jacket on my lap in the car journey.
I can't imagine they didn't see this big white sticker but I hope they didn't think I did it deliberately in an attempt to be 'the fun new guy'. Strangely they all seemed to remembered my name.
Everywhere's within walking distance if you have enough time.
The name tag thing made me think back to a job in a previous life. I had a new colleague who was a charming young lady, but about whom someone said (unkindly but not without a grain of truth) "I think the little hamster's gone to sleep in his wheel." This young lady told me that she had a hard time remembering people's names. I suggested she just glance at their name badge, and soon she would remember them. She said "I would, but some of the men clip them to their belts, and I'm - er - embarrased to look there in case they think ..." and she traled off.
I smiled, but couldn't offer a better solution. (I'm sure the guys would not have objected. But I'm equally sure she feared - with reason - that her intentions might be misconstrued).
