Route 1 - current job at managers level but not paid a managers full wage. Contracted 37 hours a week but work upwards of 40. Understaffed and stressed and no progression routes BUT recognised as a manager, management team are lovely and I know the job inside out.
Route 2 - new job but it begins as a 8 month fixed term contract - normally people are then moved onto a permanent contact but the official line is down to performance and business need, in an area I have never worked before, very very large organisation and not a management role BUT WFH options, pay is more, more room for progression into lots of different areas, less hours a week, less stressful.
YABU - stick with the current job
YANBU - give it a good go!
