What to say when asked why you are leaving?

[ForBrickSnake]

I visit clients in their home and am now learning to set up being self employed. I've been asked by manager not to mention anything but I think in my last but one visit I should or need to be prepared to answer why if my boss chooses to let clients know while I'm still in post. I'm leaving because the job physically exhausts me but can't say that. Any advice please.

Talk excitedly about your new venture?

Of course yoy can say that. Lots of people leave physical jobs because it gets to be too much. I think it would be incredibly unkind not to let clients know you are going. I very much doubt they will ask why directly. More likely they will ask what you are going on to do instead. But if they do 'being on ym feet all day is taking its toll on my joints' or whatever the exact physical reason is

You talk about your future :)

Manager just doesn't want you to trash the current service.

The thing is I'm going to do similar on my own but choosing my hours/breaks (fingers crossed I get clients) have not told boss this. I'm not going to poach clients.

They probably won’t care why! If they ask, just say it’s time for a bit of a change.
