By way of background I've been working for my current employer (Big 4 professional services) for over 15 years. We've just lost a senior person in my team and although someone new has joined recently to make up numbers it's not a replacement as they are much more junior. I can't cope with my workload and it's badly affecting my home life and my DC/DH are bearing the brunt of my stress and anxiety.
I've been offered a job at a direct competitor who have a slightly bigger team and it's a decent pay rise. The new job is likely to be just as demanding/stressful as my current role but with more pay and a bigger team maybe I can cope better as there will be more people to share the load and I can outsource more at home. The problem is I can't get over this feeling of guilt about moving to a rival. AIBU to move for the money? Is the grass really going to be greener?
