Take
broquaint's answer, remove the assignment, add a loop and a print. Job done.
Or do you just want the code:
my %hash;
while (<DATA>) {
my @data = split;
$hash{$data[0]}->{employee_number} = $data[1];
$hash{$data[0]}->{years_employed} = $data[2];
}
foreach (sort {
$hash{$a}->{years_employed}
<=>
$hash{$b}->{years_employed}
} keys %hash) {
print "$_ $hash{$_}->{employee_number} $hash{$_}->{years_employed}\
+n";
};
__DATA__
SS123 EMP123 3
SS234 EMP124 2
SS456 EMP125 1
prints
SS456 EMP125 1
SS234 EMP124 2
SS123 EMP123 3
