Job Insecurity

I have been constantly hearing about the firing policy of most of the organisation. Many employees have been Asked To Leave (ATL) or fired by the organisation for various reasons. So many people are sitting unemployed and the number is just keeps on increasing. Also, those people who are still in the organisation, don't have any security about their job. Any day, organisation will walk to an employee and will inform him that he is no longer required by the organisation. One day you make good money and the next day, sitting at home unemployed. There is no stability, no security, no understanding, nothing! Employee are no longer treated as an asset to the organisation. They are more of a liability which they will get rid of anytime if it exceeds the limit. How a person can know when he his turn to get fired will come? How a person can judge the time he will spend in a particular organisation? In sales kind of profile, if you aren't bringing sales in first 2-3 months,
