Why do you think they see you as a threat? Because you are showing them up by doing things they do not want to do? Keep your head down and do your own work la.

Let me sum up what I see so far as to your ideal job:

- family-oriented (ie understanding boss that let's you run off as and when you need to)
- allow you to come in late, yet knock off early to catch the shuttle
- pay you better than anyone else
- a noisy friendly environment that isn't serious and businesslike

Make the decision, want money, want family time, or want happiness? You can only choose two.
