What to do when work follows you into your time

"The best advice for a manager is this: If you're not sure, or if you have any doubt that the message, email or sentence you're about to say to employees is problematic, don't say it." That advice comes from George Stern, an American workplace expert who has become something of a guru in the field thanks to social media. It is advice that virtually every career and human resources consultant would probably endorse wholeheartedly, and it may be the most basic principle in employer-employee relations. From disputes over job responsibilities and employment conditions to expectations that workers be available on days off or at night, the delicate boundaries between bosses and employees are constantly being reshaped, and it is not always easy to tell when they are becoming blurred and problematic.
