How do we help recent graduates to be successful in the workplace?

If you've been someone who has spent a lot of time working with recent graduates who just finished college and still haven't had enough work experience, you've probably seen some strange and unfamiliar behavior in the workplace. For example, you might see a recent college graduate coming to work dressed to go to the club, a new worker who doesn't realize that the CEO of a large company doesn't want to know what he thinks about the company's new brand plan. or a recent graduate who answers all his phone calls. She puts the phone on speakerphone without noticing that her colleagues were throwing her angry looks. We've all done similar things early in our working lives, because we don't do what's necessary to teach students and recent graduates how to behave in the workplace. We teach them other things like writing a research paper or conducting a lab experiment, but we don't have many clear mechanisms for teaching them the skills that will help them succeed in the first few years of work. We are content to throw young people into the furnace of working life and expect them to tackle the issue on their own, which obviously leads to them making a lot of professional mistakes while doing the job, and some of those mistakes are very embarrassing for them. We've all heard stereotypes of entry-level employees thinking they should have a spacious office or have a special assistant, but in my experience these are erroneous and highly exaggerated. But perhaps the most common thing is having young employees who have not yet realized they are now adults and do not need permission to go to lunch or leave the meeting to go to the bathroom, or who are ashamed to call their bigger colleagues names without. titles, or who are afraid to ask questions because they think people assume they already know the answers. But that doesn't mean there aren't any new employees who don't realize the nature of their role and how to behave in the workplace. Two years ago, I received an email from an intern saying that he and several other interns had been fired after writing a protest petition asking their company to relax their dress code. Apparently, they had previously spoken several times about the company's clothing conditions for employees and were told that company policy would not change, so they took the time to write a petition to raise the issue again. These interns were shocked when the company decided to finish training earlier than expected, rather than arguing with them about what to wear to work. But in most cases, recent graduates' performance is OK, and they simply need someone to explain to them the behaviors and rules followed in the workplace. It's really weird that we don't do it in an organized way! So why not do a better job teaching college students and recent graduates how to behave in working life? At the university level, there is no doubt that part of this gap is due to the fact that professors work academically rather than practically and do not have much practical experience in traditional office jobs. But why aren't employers and companies hiring these graduates doing more to help recent graduates understand how to cope with working life? And if these companies give employees instructions on things like attendance policy with sometimes boring details, why don't these companies also address the other things that will determine whether or not these new employees are successful on the job?
