Creating your own distinction between work and life is a challenge, but a fun one to tackle.  It's helpful to have a separate working area with a separate computer for example.<p>But I have to disagree with the point that it gives the employer the right to ask you anything at anytime.  You have to set boundaries.  A set schedule helps.  The easiest is to stick to the 9-5 schedule since most of the other employees will be doing that.
