People need to learn what is commitment!!!

I am real upset with what all is happening around me. People join a company, get on board, stay with a company for 10 days and resign!! Do these people understand the word commitment at all! This is just not at all professional. When people join a company, they exactly know what they will get into, what is their package going to be, etc. In-spite of that, you get a higher offer and you resign. People need to realize that the IT industry is really very small and they will meet the same people some day nor the other!
