Thanks!
Well it’s obvious I have to supplement my “full-time job” with something else once in a while, as the roofing work goes quiet sometimes and although as a full time employee with applicable rights, eg full pay regardless, the full pay only pertains to 37.5 hours a week and that is a pointlessly small amount of time/money for me. Rather find something useful to do in the meantime.
So I guess I might be driving more in the wintertime as a freelancer, we’ll see.
