Well, it's ugly, but it can be done. Would make a lot more sense to have a table of questions and a table with a single row for each response to each a question, but if you can't do that you can do something like this, extending the SUM to include all 10 columns:

SELECT SUM(IF(essc_a1 LIKE '%es%', 1, 0) + IF(essc_a2 LIKE '%es%', 1, 0))
FROM employee_satisfaction_survey_checklist
