One question often asked is availability - the need to be assured that you're there for them. I return phone calls and emails within 3 hours right now. Although I'm working full time I'm starting to work it some remotely so on days I have to be at the job office I pop out to my car and return calls by cellphone. Three hours is a good timeline for me, though I usually answer emails within the hour. Kinda juggling things at the moment
