In works time or in your own time

For me it depends.
If I’ve been off for a week I’ll pop to the yard on Sunday and pack all my stuff away neatly.
But if I’ve just had the weekend off I don’t have a lot to muck about with so I do it during the time my cards in for my walk around checks.
I know some will think it’s stupid, but I find it far less stressful knowing that all I have to do is turn up and do the job. No messing around.
