I started a new job around 7 months ago and hate it. Its getting progressively worse and I have decided to leave. I know that I am very fortunate that I can do this and am very grateful.
My issue is what can I say if they ask why? I usually have another job lined up when leaving a job but I don't this time. The job is the same job I have been doing for the past 10 years so I can't say anything about it not being for me / not what I expected.
