Who knows, maybe not so much, on other hand we always spend more time and effort for our work if we love what we do. I know that from myself, that sometimes I even come on weekend to make sure that everything is done and dusted, then during week it is much easier to concentrate myself on other important staff. I actually loved the fact that on weekend it is no time pressure nad I could make some nice cup of tea with buscuits and also to chat with some of people who also were there for weekend sometimes we have a team covering weekend.usually I make sure that my part of work is done before 3PM then the rest of my day is free for my weekend activities with friends :)
