What's wrong with my code? I figured it out! No need to reply :)

Following is my code. No matter what day I put in the console.log() it returns the default message. Where have I gone wrong?

const getSleepHours = day => {
switch (getSleepHours) {
case ‘monday’:
return 8;
break;
case ‘tuesday’:
return 9;
break;
case ‘wednesday’:
return 7;
break;
case ‘thursday’:
return 6;
break;
case ‘friday’:
return 5;
break;
case ‘saturday’:
return 10;
break;
case ‘sunday’:
return 12;
break;
default:
return ‘You had enough sleep’;
}
};
console.log(getSleepHours(‘saturday’));
