Our office is small, but we dont do PTO or any type of time management. People take the time off they need to get their work done, whenever that is. The rest of the office helps out to make that happen. I know it wouldn't work for big corporate settings, but it honestly works better than any PTO or FTO system in small-office settings. As long as you hire responsible people, nobody abuses the system. I might take 4 weeks off one year and then only 2 the next year, all depends on my work load and what types of vacations / trips I want to take.
