I'll have in mind the considerations below:
First off, this piece, published in a local newspaper regarding child protection week. A lot of sense for general people relationships.
Philippians 2:3, 4
Do nothing from selfishness or empty conceit, but with humility of mind regard one another as more important than yourselves; do not merely look out for your own personal interests, but also for the interests of others.Phillipians 2:14,15
Do all things without grumbling or disputing; so that you will prove yourselves to be blameless and innocent, children of God above reproach in the midst of a crooked and perverse generation, among whom you appear as lights in the world.Galatians 5:22f
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, 23 gentleness, self-control...2. Be involved with people, take a genuine interest, and be open to their interest in you. Have interesting things to say, listen to what they say with real attention. Have interests to discuss outside your church involvement (it can be offputting if you always give your weekend report as "I went to church with friends", when people may see a more approachable you if you can say: "I went gliding, with one of my pals..." You get the picture.
3. Go out with work groups at least sometimes. If you don't like the venue, only stay a short time; if you don't want to drink alcohol don't and be firm, polite and confident in refusal (you might tell them its a carcinogen!)
4. Work well, committed to your employer's business.
5. Seek to know and be known, to listen attentively to what people are really saying.
6. As you get known certainly don't avoid your Christian commitement, but ensure that you introduce people to your beliefs and values in an appropriate context.
