If we talk generally then unemployment are three types-
Frictional unemployment
Structural unemployment and
Cyclical unemployment
Frictional unemployment rises when a person try to find a new job or shift from his old job to new job
Structural unemployment arises due to the technological advancement which causes the mismatch of the supply of the workers in the market in the demand of the workers
Cyclical unemployment rises due to the business cycle up and down
Yes it is true that unemployment is seen as undesirable by some persons because it cannot be neglected upto certain level
For example up to a certain % structural unemployment and frictional unemployment cannot be ignored because in any economy every time people will move their from their old job to new job or if there is technological advancement then there can be lay off of the workers as well
Even the United States data says that up to 4% of unemployment is healthy for the economy
