hello, could you please check this writing as follows. If somewhere is wrong, please correct . While some people may believe that businesses should offer lifetime employment. It is far more realistic for company to hire workers for varying periods based upon their own business needs. Two important reasons are employee motivation and company flexibility. The first reason why companies should hire workers for temperately period is that to inspire employees to work harder. As a profit organization, company needs to create benefits constantly. Workers should be trying to make more profitable for company. Moreover, companies should apply a performance oriented evaluation system. If workers know that their continued employment is contingent on their successful performance, they will be more motivated to achieve their stated targets.merit-based system could encourage workers more aggressive for individual performance. According to research. Companies which focus on results are always create high performance than others which not. Therefore, companies should primarily hire workers based upon their accomplishment. Second, hiring workers in their entire lives is unrealistic because companies need to be adaptable. For example, during some periods sales expand and a firm grows, during such times, it needs to be able to hire additional workers. In contrast, at other times its sales decline and profits shrink, during periods like this, It needs to be able to cut costs and reduce staff. Moreover, it allows companies to survive longer during difficult times and that was proven by history. Look back financial crisis of 2008, many companies have overcome this unexpected catastrophe by lay off or fire their workers, by contrast, some firms went bankrupt because they did not perform it on time. Thus, firms should be more flexible on hiring workers. For all of these reasons, hiring employees based on their business needs is important, because it makes company more flexible and encourages employees working harder.
