Both can be used to invite users who are new to the TikForce platform into your organization.
“Add Worker” (Worker/Manage Worker) should be used when you want to add a worker (who isn’t already on the TikForce platform) into your organization. You have the option to immediately also select a position for this worker.
NOTE: “Add Worker” will not let you add if the worker is already on the TikForce platform. You can also “Bulk Add Workers”.
“Invite Worker” (Worker/Manage Invites) can also be used to invite a worker to your organization, whether they are outside the TikForce platform or already in the TikForce platform*.
However, until they have accepted the invitation to your organization you will not be able to assign them to a Position. You can also “Bulk Invite Workers”.
