This option for staff to elect, or for business to choose would further comply with HR guidelines regarding "work that occurs off the clock". Receiving notices of work activity that may or may not trigger an employee to do or think about work is cause for employees to have grounds to "be doing work from home".

Employers in regions with stipulations on this should create company policy explicitly stating that notification of client booking, cancelling, rescheduling are to be accepted during work hours only. In the case that they would like real time notice of this regardless of work-state, they can enable this option voluntarily.

Additionally it would be great if there were options like:

When clocked on or schedule resumes, receive batch notice of all changes since last worked.

Receive daily; Hi Charles, since you last worked you received 12 client self bookings, 22 staff created appointments, 2 cancellations, and 3 reschedulings. Have a good day at work!

Quiet hours for notifications (staff select), to not receive notifications until certain hour every day.

Quiet hours for business (whole location), to suspend notifications until set hour on next day.
