Unlimited PTO is a great benefit as long as people use it (and management leads by example). I found this to be generally true at EnerNOC.
"Unlimited" but pressures of the job cause employees to take about 15 days or more. Some managers abuse it, taking over 6 weeks a year.
Unlimited PTO, at manager's discretion. Some people abuse it and it slows down progress.
Unlimited PTO and 10 EnerNOC paid holidays.
