The current system is that workers must have a medical check-up before starting work. This is great for the worker, but it brings a few complications - no "today-tomorrow" employment, not worthwhile for very short-term employment, students have to be managed as a separate group with exceptions, etc.
I propose to draw up a list of the jobs that most workers do (standing, sitting, computer work, lifting objects up to 25 kg, etc.) and to have an examination to certify the worker's ability to do all these basic requirements - but this certificate would be valid for three years as before, regardless of the employer (so if you change from one office job to another and you have had an examination a year ago, you do not need a new examination for two years). For occupations with specific requirements (psychological examinations, etc.), an additional examination would be carried out according to the additional requirements of the specific job.
For students, such an examination would be carried out as part of the regular systematic examinations already carried out during their studies.
This would simplify recruitment for all and reduce unnecessary checks. This would also be the first precondition for putting student work on an equal footing with other forms of work, as this rule would also apply to them in the same way as to others.
