There is "on" time and "off" time. During "on" time, you are customer-facing. You're performing a service - normally what you would consider doing your job. But you're physically visible to customers, or they're directly waiting for your responses, like on a phone call. You're so visible in this fish bowl that you're like an actor or news anchor, and must be mindful of every action. Some jobs, like retail checkers or bartenders, are "on" for most of their work shift. In a way, it's like P time. Other jobs are "off" jobs, where you're never seen by customers. This is time spent "in the workshop", building demos, displays, and developing presentation. It's like NP time, and any communications are asynchronous. You don't see customers, sometimes don't see coworkers or boss, and might even get to be alone. Many jobs have a mix of "on" time and "off" time - where you may take a client call, then work independently to make what the client wants.
