“sustained wage growth for lower-wage workers by skills development, increased productivity and higher service standards”

And I have to say people have not been taught how to clean is a correct statement.
Cleaning a bathroom is not hard but there are certain things that need to be done. Especially if you are cleaning a community bathroom. Don't think the course should cost that much but a paid course to learn how to clean in general and how to clean professionally is undoubtedly needed.
