Try this:
SELECT first_name,work_email FROM tb_contacts WHERE tb_contacts.work_email IS NOT NULL;
Or if there are also blanks among those e-mail addresses:
SELECT first_name,work_email FROM tb_contacts WHERE tb_contacts.work_email IS NOT NULL AND tb_contacts.work_email != '';
no difference
Then you probably have email addresses that exist of white space only. You should probably put a constraint on that if undesirable.
Try using a regular expression like so:
SELECT first_name,work_email FROM tb_contacts WHERE work_email !~ '^[[:space:]]*$';
