In some implementations, managing the environment state component 108 may include maintaining queues of the units of work assigned to the users. The queues may be presented to the users in a user interface of the collaboration environment to facilitate access to the units of work via work unit pages. Individual queues may represent the units of work assigned to individual users organized in an order based on the individual end dates and/or other dates (e.g., start dates) and/or other ordering. Individual queues may be presented in a user interface based on one or more of a list view, a calendar view, and/or other views. The calendar view may be a calendar view by week, by more than one week (e.g., 1st through 15th), by month, by more than one month (e.g., May through July), and/or other calendar views. Units of work may be represented in a calendar view by user interface elements (e.g., icons, calendar entries, etc.).
