If you wait for a long time this damage your working morals. How would you say this in English?

I don't know what you are trying to say, maybe this:

If you wait for a long time, your moral principles will be eroded.

I waited for someone for a long time, my moral principles were eroded because of this. Does it make any sense?

sundarnazI waited for someone for a long time, my moral principles were eroded because of this. Does it make any sense?

No. Someone whose morals are eroded would engage in corrupt or sacrilegious practices.
I doubt that waiting for someone would cause such a descent into immorality..

sundarnaz What is the opposite of "high morals"

Do you mean "http://education.yahoo.com/reference/dictionary/entry/morale"?

enoonDo you mean "morale "?

Now that's a thought. It makes much more sense with morale. That is a completely different word.

The opposite of "high morale" is "low morale."
