Dear Kusum,
You could have given little more information. Why are you asking this information? Are you working professional or student?
Which employees face work pressure? Why they face the pressure? Have you or anyone done study on work pressure? Does the pressure develops because of excessive targets or excessive working hours or lack of skills? On what parameters do they measure the business performance?
There are so many questions. Please give us complete information and then only it will be possible to give proper reply.
Thanks,
Dinesh V Divekar
