They tend to assume this because for all they know you have been watching TV all day while you were on the computer connected remotely to the office., So, in their little minds you not have NOT really put in an "honest" days work. I know this is not always correct for all managers. but I am just pointing out the general mindset here. I have seen it too many times in the past from a lot of management over the years. If you are working from home, you got it easy as far as many managers are concerned. Therefore, contacting you at midnight shouldn't be a problem. Thats just the way many of them think. 😀
