there isn’t anything wrong with four ten hour days, a lot of people like nurses do a lot hours in a few days then get three or four days off in a row. Like nothing wrong with working from home if it fits the business.
As long as it’s not MANDATED then who cares.
A former employer of mine once instituted a four-day work week for his professional services company. It lasted for several weeks before he shut it down. The trigger for the shutdown was the Friday when he was the only one in the office and realized there was nobody answering the phone when a client called. Its kind of baffling that he didnt think of that beforehand.
