job wearing me out

[ForBrickSnake]

Is it normal to be absolutely exhausted/in pain by the end of working week? My job was advertised as some housework but it's more like 90%. I'm a few stone overweight so I know that does not help but most of my weekend is spent recovering! I think my job was mis advertised. Just ranting really.

What role was advertised?

In the last couple years I’ve been struggling with knee pain and because I work in a nursery it is made worse through the week.

This job is affecting your health and if it's causing pain it's time to move on as that is absolutely not normal.
I'd be actively applying for other roles and I'd tell my manager that I need to move on as the job is not what I expected, is affecting my health and I would never have taken it if I'd known how much physical work was involved
