So, I figured I would post this question because its been really bothering me
I've been working in a Help Desk position with an IT company for over an year and recently interviewed for a Network Engineer position a month ago (Same company different departments). I was told a few days back that they wanted me to start in a week. I was never given an offer letter nor discussion was brought up regarding salary.

It is me or is not a proper way for management to handle a move?

Anyhow I don't feel that this position is a lateral move from Analyst to Engineer. I am currently getting paid by the hour, don't work weekends and have a very nice 8 hour shift with the helpdesk.
The new position requires me to travel every 3-4 weeks to help configure and setup networks world wide. The new position requires to stay afloat with constant studying and working on stating ahead with networking terminology etc. Even during the interview I was told that someone at a CCNA level will have to work hard in this new position.
So my dilemma is should I take this position if they don't offer me a raise? What can I use for leverage to make them offer me a raise etc?
I am trying to way my options because the I feel the knowledge I gain in the new position will help my future career but at the same time I don't want to put in hours of work and be away from loved ones to get paid the same crummy salary I could be working my current 8 hour a day job.
Any feedback is appreciated
