Undercover Boss (Season 5)

Under the pretext of a documentary about an unemployed person looking for a job to get back into the workforce, a boss (different in each episode) dresses up and then, under the pretext of a filmed report, carries out short internships in various jobs in the company he runs. He is accompanied by one employee per trade category. The fact that the employees know that they are being filmed can induce a Hawthorne effect. The program ends with the employees who accompanied the trainee being called to the company's general management. The boss lists the criticisms and anomalies, then ends by praising the qualities of his employees: dedication, motivation, etc.
