Agendrix has a functionality that lets you know if employees have seen their schedules. 

For it to work, the schedules have to be published.

When employees will have seen their schedules you will notice an eye on the shift that has been seen. 

Note: Employees do not know that you have this information

If the eye is like this, that means the employee has not seen his schedule

If you hover the shift you will see the hour as well as the date that the employee has seen the shift!

It is also possible for employees to confirm their shifts for you to have an extra confirmation on their end.

It will appear as a check rather than an eye in the schedule.

You can also hover over and find out the exact moment de shift was confirmed by the employee

CAREFUL
Confirmation is optional for the employee. He is not forced to do so and he cannot refuse the shift. You will simply have the eye appear if he has seen it but did not confirm it.
