Advice for better time management typically includes saying no to meeting invites or checking email less often. But actions like these might adversely affect your colleagues. So before starting a new productivity regimen, get input from your coworkers and experiment with different techniques to see what might work for everyone. If your approach is going to infringe on someone else’s work, ask how you can make it up to him. You also need to make clear what you’re doing and why.
If you want to decline meeting invites, share your reasoning: you’re working on a big initiative or other members of your team are attending. And because changing how you work can be disruptive, time your new approach wisely — not during a sensitive crunch period.
