You can use this code in .htaccess on olddomain.com:
RewriteEngine on
RewriteRule ^employee-scheduling-software\.html$ http://newdomain.us/employee-scheduling-software.html [R,QSA]
Since it ^employee-scheduling-software\.html$is a PERL regular expression, you need to escape the dot in ".html" with a backslash ( \.).
employee-scheduling-software.html . , :
RewriteEngine on
RewriteRule ^(.*)$ http://newdomain.us/$1 [R,QSA]
