> I actually turned off all slack alerts and disabled notifications on my phone

Nobody should be reachable after 5pm unless they work the night shift and/or being paid to be oncall.

That you “actually” disabled these alerts points to a culture problem at work. A work app should not even be installed on your mobile.

Put your workstation to sleep at the end of the work day and don’t wake it until the next one. As you said, they can call for the once in a year emergency.
