According to Above the Law, however, one Biglaw firm recently reminded its employees that they need to check their daily emails while out on leave.
There is ample time in the day for everyone on leave to monitor their emails daily and to forward any emails requiring attention to the appropriate members of the litigation team. If you are someone who has not been monitoring your emails daily, please do so as soon as possible. If, for any reason, you are unable to perform this minimal task on a regular basis, please advise.
This is not just a terrible employee relations practice, it's also potentially illegal.
