In some implementations, units of work created by, assigned to, and/or completed by the users may refer generally to a linking of the units of work with the individual users in the collaboration environment. A unit of work may be linked with a user in a manner that defines one or more relationships between the user and the unit of work. Such a relationship may connote and/or be a result of an action (past, present, and/or future) of the user with respect to the unit of work. Such actions may include one or more of creating a work unit record for a unit of work, being assigned to participate in a unit of work, participating in a unit of work, being granted access to a work unit record of a unit of work, adjusting a value of a work unit parameter of a work unit record of a unit of work, being assigned a role at the unit of work level, and/or other actions.
