A task has one assignee – the person who owns it – and any number of collaborators, the people who care about it.

​
Assignee vs collaborator

Use the assignee for “whose job is this”. Use collaborators for reviewers, second pairs of hands and anyone who needs to follow along.

​
Assign a task

1

Open the task

Click the row or card. The side panel opens.
2

Click the Assignee field

It is in the Details section. The picker is searchable and shows each person’s avatar.
3

Pick a person

The change saves immediately.
You can also change the assignee straight from the project List tab – the Assignee column is an editable picker on every row.
When the task is not yours, an Assign to me link appears under the picker in Details. One click takes it.

​
Add collaborators

Collaborators live on the full task page.
1

Open the full task page

Click the diagonal arrow in the panel header, or the task number in the breadcrumb.
2

Find the More card

It is at the bottom of the right rail.
3

Use the Collaborators picker

Choose as many people as you need. Each shows with an avatar.
If the workspace has no other members yet, the field reads “No members to add yet.”

​
Assign several tasks at once

Select the tasks on the board and use the bulk bar’s Set assignee dropdown, then Apply. See /tasks/bulk-actions.

​
Who you can assign to

The picker only offers people you are allowed to assign work to. Someone whose supervision scope covers only themselves gets a list of one. That list is decided on the server, so it is the same list wherever the picker appears. Only members of the current workspace can be assigned. An assignee is validated again on save.

​
What happens next

When a task is assigned to someone other than you:
  • They get a task assigned notification, through the channels they have turned on.
  • The task starts appearing in the right day bucket on their Tasks page.
  • Their home-screen widget refreshes.
You are never notified about your own click. Assigning a task to yourself sends nothing. Reassigning a task notifies the new person. Re-saving the same assignee sends nothing.

​
Example

Priya Raman creates “Homepage wireframes” on Bluebird Coffee – Website Redesign and assigns it to Sarah Lin. Sarah gets a notification and the task shows up in her Today bucket on the Tasks page. Priya adds Jonas Bergman as a collaborator so he can see the layout before he builds it. Jonas is not notified and the task does not land in his day list – he follows it through the comment thread instead. Later the wireframes are handed to Ana Ferreira. Priya changes the assignee; Ana is notified, and the task leaves Sarah’s day list and joins Ana’s.

​
Options and settings

The Details picker has no “Unassigned” option. You change an assignee by choosing a different person.

​
Permissions

Remember that a capability and a scope are two different things. time.viewOthers says you may look at other people’s work. Your supervision scope says whose. Both have to pass. See /concepts/supervision-scope.

​
Common questions

No. One assignee, so ownership is never ambiguous. Add the second person as a collaborator, or split the work into subtasks with different owners.
Being a collaborator does not on its own trigger a notification. Mention someone with @ in a comment to reach them – see /tasks/comments-and-mentions.
Either they are not a member of this workspace, or they are outside your supervision scope. Check the roster at /settings/team-members.
No. The Client role holds no delivery capabilities and never appears as an assignee.
The tasks stay where they are, still assigned to that person’s record. Reassign them from the project list or with a bulk edit. See /team/remove-a-member.

​
Troubleshooting

The server validates that the person is a member of this workspace. If they were removed between the page loading and your click, the change is refused. Refresh and pick again.
You do not hold time.viewOthers. The page shows your own work only, and that filter cannot be widened by hand.
Assigning notifies once per genuine change. Re-saving the same person sends nothing. Two notifications means the assignee changed twice.
