Keep a log of the birthdays, hobbies and names of spouses and children of colleagues, managers, team members and customers.
I learnt this from a guy who did executive search. People remember you, when you remember what is important to them.
When I've lead teams it's one of the first things I find out - note down when someone says "yeah Gary that's my hubby, he's super into gaming"
Gary (husband.)
likes gaming
When you're a manager, your teams families, partners and friends know your name. Reciprocating that - learning who is important to them - is really important.
Bingo. I think that's the key to it - if you do it with the intent of getting something from someone, people will work that out pretty quickly and resent it. It comes over as being...greasy.
If it's done from the perspective of having genuine interest, care and empathy it makes it easier to work as a group.
Has this ever backfired on you? While your motive is wholesome, I could see the practice itself seeming creepy. Like keeping notes of someone else's life.
I do this too; it's a great way to get to know your team and develop genuine bonds. People generally enjoy when you show signs of caring and interest in them beyond their work role.
