Omega.
I believe you are chosen by Christ to be saved.
But I'm also worried about you. It's really cool that you're so pumped up about Jesus, but at the same time, you seem kinda paranoid. I really don't want to discredit you, you've really helped me in my time on this forum. But I just get the feeling you need to chill out a little.
If you find someone in your job who claims to be a Christian, you should be GLAD!!! Not worried!! Mate, try and establish a real, normal, human relationship with her. And then the love of God can be made known by your actions and behaviour! You REALLY don't have to go all out and preach about the second coming and stuff which is interesting, but of no import to the serious stuff in life, [that is how Jesus is our Lord and Saviour].
A Christian friend in a secular workplace is something to be glad about!!! Many Christians would give their hind teeth for someone even mildly sympathetic to their views in their workplace.
Whatever you do, do NOT alienate these people. Meet them. Talk rationally with them. Have FUN with them. They are good people, and together hopefully you can further your knowledge of our Lord.
I pray for you Omega, that you don't get carried away and can balance the love of God with the realities of the life he has deigned necessary for us.
You're on the path
Just don't get carried either side of it.
