Assigning means a manager or supervisor chooses an employee to work a specific shift. This is a top-down approach where the decision is made by someone in a leadership role.

Inviting, on the other hand, means that an employee is given the option to work a specific shift. They can either accept or decline the invitation. This approach is more flexible and allows employees to have more control over their schedules. Additionally, inviting can be used to confirm that the employee has seen and accepted the shift, ensuring that the shift is covered.

In addition to the options previously mentioned, another way for users to manage their shifts is through open seats. If self-scheduling is enabled, users can sign up for shifts independently based on the role they are allowed to work. This allows for more flexibility and autonomy for team members, as they can choose the shifts that best suit their schedules and preferences.

In summary, assigning is when a manager chooses an employee to work a specific shift while inviting is when an employee is given the option to work a specific shift.
