Well, there are two reasons for this contradiction:
- What they don't say in the news: There is a lack of cheap experts. Companies are searching for people who work for a banana and wonder that the only candidates showing up, are apes.
- Companies always try to achieve more with less people. This implies that you need good people because only the best and most efficient workers can achieve more than most of the others. So many workers available but not matching the high performance requirements. But even if the best workers out there achieve more, nobody can run on 150 % for years. So often workers are "consumed" in the long run. You can work at full power and full speed for some months, maybe for a few years, but there are mental impacts and impacts on motivation and health. At the final end when your energy is exhausted you will further be criticized for your decreasing performance. So the already low number of very good people available is also decreased by those who end up with burnout and by those who take their own lifes.
In our consumer society, employees also tend to be consumed and companies do believe the newspapers when they write of high unemployment rates. They might think that there is enough human resource left, not considering that they cannot fit the high expectations.
But let's assume, a company needs a new worker, what are the required tasks?
- Prepare a job description
- Outsource hunting for appliers or do it on your own
- Make final interviews (or more if you do hunting on your own)
- Prepare contract
- Some other administrative work (preparing clothes, creating user accounts, print business cards, ...)
- Send new employee to courses or have a peer explaining everything
- Accompany employee in the first few weeks (e.g. by introducing to new clients and projects, ...)
- Wait until new employee has adapted to new situations and finaly reaches performance of the previous employee
Yes, everybody can be replaced somehow, but every replacement required, will cost time and money! To put those costs into effective numbers is difficult and that's why in many cases there is no awereness of the real impact of a staff change ("what cannot be put into numbers, cannot be controlled"...).
Now that we talked about people you can apply this to material, machines, software modules, technologies or structures accordingly.
The best strategy therefore is:
- Choose wisely your workers etc
- Do the required maintenance work (motivation etc)
- Don't consume them
