I see the survey results across a pretty big portion of the organization so I understand my answer is one of the lonely few. I always answer ‘no’ because I really don’t have a best friend at work.
A best friend is someone you like, enjoy loads of spending time with and maybe most importantly can trust with just about anything. It happens that I don’t really have true friends at work but I have people I care for and would be there for if they needed. That doesn’t make us friends, it makes us decent people.
I try to keep a healthy level of separation between work life and home life. I don’t want to know office gossip because I want to be able to continue looking at my colleagues as professionals. I also want the diversification that should I ever leave the company my whole life won’t be blown up because it was attached to the company.
