employee和employe哪个比较常用
两个都是雇员的意思,哪个在日常生活中使用更广泛呢

An elderly carpenter was ready to retire.He told his employer about his plans to leave the house-building business to live a more leisurely life with his wife and enjoy his extended family.He would miss the paycheck each week,but he wanted to retire.They could get by.
The employer was sorry to see his good worker go and asked if he could build just one more house as a personal favour.The carpenter said yes,but over time it was easy to see that his heart was not in his work.He resorted to poor workmanship and used inferior materials.It was an unfortunate way to end a dedicated career.
When the carpenter finished his work,his employer came to inspect the house.Then he handed the front-door key to the carpenter and said,"This is your house...my gift to you."
The carpenter was shocked!
What a shame!If he had only known he was building his own house,he would have done it all so differently.
So it is with us.We build our lives,a day at a time,often putting less than our best into the building.Then,with a shock,we realize we have to live in the house we have built.If we could do it over,we would do it much differently.
But,you cannot go back.You are the carpenter,and every day you hammer a nail,place a board,or build a wall.Someone once said,"Life is a do-it-yourself project." Your attitude,and the choices you make today,help build the "house" you will live in tomorrow.Therefore,build wisely!
