3 years ago, my company gave me 2 cell phones, 1 for office hours as I was working on site for a year with lease up, and one for emergencies only. Complete pain in the neck carrying 3 phones during the day, and 2 on weekends and evenings.
We now have an phone system that forwards all office voicemails to our email, so we changed the emergency policy and requested that all tenants call the office to leave a voicemail or email me. We were offered a $50 incentive to put our work email on our personal cell phones. One phone for everything and no personal information was given out, completely worth the incentive and the reduction in phone lines/numbers. It also eliminated a million ridiculous calls on the "emergency" line.
