Your staff can create their own log-in to access their calendar.
To set up your staff make sure you have this feature turned on. Go to your Settings (My Business > Setting) and under the Staff section toggle the "Can customers book a specific staff member?" button to Yes. Don't forget to save your choice.
Then you'll have to set up your staff members in your account. Go to your Availability Page (My Business > Staff & Availability) and invite your employees by email and they'll be prompted to make their own mini-profile in your MyTime account.
