Fuck the trainees.
In the company where I worked for a long time, the trainees were very loved. But, first, they were very tough and selected in several stages. And, secondly, they were thrown down on a non-urgent, tiny, mutant job, which steals time from truly qualified professionals. And the world will not collapse if the trainer sets up. We, the trainees, checked the sites at the time the links were beat, chased them through different browsers and gadgets to understand what was floating at the same time. Salesmen helped senior colleagues to update the presentations, lawyer assistants further checked the details of the contractors, all kinds of registers of contracts were put in order. And everyone was happy. Gradually, more interesting and responsible tasks were given, the best workers were taken to the staff, or even promoted over time. Just at some point in life, the firms tried, developed, and then arranged this whole system so that it worked as everyone would like. They say it took some effort and time, but it paid off 100%.
