If you have only Tempo Timesheets installed, you can plan time for yourself and see only your own plans in My Work.
To plan time for others, you need to have Tempo Planner installed and the Manage Plans permission for the relevant team.
My Work shows you the agenda for your week at a glance. This includes all work planned for you by your Team Lead or Resource Manager. My Work is also where you can request time off and organize your own plans. At the end of the day, you can easily log time to your plans.
If you usually plan meetings and other events in your Google or Office 365 Calendars, you can connect those calendars to My Work. These events then appear in My Work, making it even easier to plan your work. When the events are finished, you can quickly log time to those Calendar events in a single click - see Logging Time to Your Activities.
Select My Work 
in the Tempo sidebar to open it.
To plan time for yourself in My Work:
Click either List or Calendar at the top right.
Hover over the + button at the top of a day where you want to plan time, then click the Plan Time button.
Fill in the Plan Time form, then click Plan Time when you're done.
A plan card is created and displayed on that day. In the List view, it is sorted under the Plans group.
To edit the plan, see Editing Your Plans.
When the plan has been completed, click the plan card to log time to it.
