Long story short, I have been employed at my current company for two years now. Generally I have felt supported and been happy with the company, though my position has changed recently to where I don't feel like they have my back and I can't necessarily count on them. They offered me an opportunity two years ago when I didn't have one and I am grateful to them for that. That being said, I have a baby on the way and I need the stability of a salaried position and not a mostly commission based job.
I have found and been offered a position at another company that I would like to accept. Pay is great, good benefits, great work environment, whole 9 yards. I really wanted this job for a while and I'm ecstatic to have it offered to me. That being said, I need to resign my position at my current company. I am the only salesman in my region and I know this will leave my current company in a lurch. What is the best/most diplomatic way to resign my current position and be able to maintain a good relationship with them? The new company wants me to start ASAP.
