One of the primary reasons people negotiate is to allocate scarce resources. And one of the scarcest of all resources is time. So it should come as no surprise that protecting our time—much as it seems little like a negotiation—is. Indeed, I would go so far as to say that our success in preserving certain amounts or periods of time strongly shapes the negotiability of our lives.

With that in mind, let’s consider some lessons from negotiation research with direct relevance for protecting our time:

1. Define your positions and interests: You can’t protect your time unless you know exactly what you want to protect—how much or what period? And you won’t have much success in protecting it unless you deeply understand why you need to. A few extra minutes at the office doesn’t seem like much unless you link it to your inability to coach your kid’s soccer team. And your interest in coaching soccer highlights new (and somewhat obvious but surprisingly underexplored) solutions like coming in earlier instead of staying later.
2. Establish a reputation: After deciding how much time to protect, establish a reputation for protecting it! As in any negotiation, a true bottom line—a latest possible hour in the office, unavoidable family commitment—shouldn’t slip. And bolster your reputation for protecting your own time by showing an unwavering respect for other people’s right to protect theirs.
3. Propose solutions: It’s easier to protect your time if you replace a “no” with a “no but.” That is, when someone tries to encroach on your time—as someone always will—don’t just reject them in a flurry of frustration. Reject their specific request but seek to satisfy their underlying interest. “No, I can’t come in on Saturday because I’m coaching my kid’s soccer team. But what if I hustled and got everything done on Thursday? Or stayed late on Friday? Or took the Saturday call from home?” It’s not rocket science, but it’ll elicit a substantially warmer response.
4. Highlight the win-win: It won’t work with everyone, but certain time-encroachers may be convinced by appeals to their enlightened self-interest. “It’s good for both of us if I set a regular schedule—that way, we’ll both know what to expect, I’ll always avoid the traffic and have more time to work from home, I’ll do a better job in the long-run, etc.”
5. Find complementarities: Maybe you want to leave early for soccer practice and a coworker wants to come in late to get their kids to school. Or you feel dead-tired in the morning and productive at night, whereas a coworker feels the opposite. Reaching an arrangement with complementary parties like these might just allow everyone to protect their preferred periods of time while providing continuous coverage of the workload.

As with so much of life, then, protecting our time is a negotiation, and the lessons from negotiation research can make life negotiable. With that, I’ll take no more of your time.
