We're normally M-F, but there have been times when we've put in some weekend hours. Usually, weekend work is required if we're integrating a new system, doing a largescale product merger, or we're acquiring a new firm where we need to test to make sure everything transitions smoothly. A couple of acquisitions caused a massive influx of client work where we had to put in weekend hours for several months. Nobody was happy, but the work needed to get done. It's too bad that all of that occurred before we implemented work from home alternatives.
Ages ago, I worked in a restaurant. Weekend work was pretty much a given.
