I have no problem working on a Sunday. I used to do it on residentials quite a bit when I was busier. The only residential I do now on a Sunday is a house where they have counselling clients visit during the week and need to preserve confidentiality. Having said that, I do a fair bit of commervcial on a Sunday. In general, I try to compress them into one Sunday per month so that I get other Sundays off. Sometimes though it's too much for one Sunday (i.e. those months where the monthly, bi-monthly and quarterlies coincide twice a year) so when I see that coming, I bring some of it forward to the Saturday. I do take some time off in the week to get a bit of rest. As I live on my own, there aren't any family issues about this.
