I was speaking to a friend of mine this morning and she mentioned about a very simple idea that she had heard from someone on building better relationships with your colleagues in your organization.
The idea is to have lunch with one new person in your organization every week.
(The duration of the implementation of the idea would be a function of your continuity in the organization and the number of people working there )
I am sure the creative minds would be able to work around this idea to come out with several interesting variants.
I loved the idea ! :)
