Since the announcement that teachers would be charged for parking in schools, there have been lots of discussion on equating the parking fee to economic theory and system equations (Teachers tarred with unclean wage: Seah Kian Peng; May 19).

As the hidden work that is performed by teachers (out of their normal work scope) is difficult to quantify, the teachers have no choice but to move on.

However, in school, teachers teach students to respect their elders, be thankful for the guidance they are given and be grateful for what others have done for us.

All these teachings are geared towards building a good moral foundation, without which economic reasoning is zero, not to mention anything about growth and progress.

It is clear that Mr Seah Kian Peng's school taught students like him well and built a good moral foundation, including on not biting the hand that fed you and contributed and moulded you into the person you are today.

Teachers are asked to teach good morals and values, but we do not put them into practise.

Of course, we must make decisions based on facts and figures. But at times, things cannot be quantified - a good moral foundation is one of them.

A good moral foundation which teachers help to build in students outweighs whatever dollars and cents that are used to formulate and implement the parking charge.

Let us review the parking charge for teachers to reflect that we are practising the good that teachers are imparting to the next generation.
