I'm not exactly an expert but seeing that most of this kind of threads go unread, I'm willing to help to the best of my abilities.
If you like you could check out my texts maybe you see something I myself would have missed.
?= proposal for a supposed error, doesn't mean that's correct though
Is there a? perfect company? What is the best form of? management? Why do many employees only work shortly in a given? company? It is increasingly necessary for? companies to change their relationships with (del'd the) employees (del'd ;) therefore (del'd comma?) they need to increase the levels of trust and workplace friendships.
"The best place for working is where you trust (del'd in§) your boss, (del'd whatever was here§) have pride (§) and like what you are doing; moreover, you like the people you are working with " as Robert Levering, creator of Great Place to Work Institute who,§ after 20 years of research and writing about the people working§ in the companies, has identified the many benefits that come from good work’s friendship [you might want to look into the term working atmosphere/climate].
The work advantage (don't understand what you want to say with this) is the relationship between employees and management. For this kind of relationship to be successful, it trust is a necessity?. The management should show the employees its capacity of facing their challenges so as to obtain more commitment of the employees to the company’s (unsure about the apostrophe) decisions.
It is important to say§ that this method has disadvantages, because the management needs to hear (del'd hard, look for smthng more appropriate) criticism without punishing its employees, because they need to feel that are members of the same team.
All things considered, I believe that the Great Place to Work (if you are not talking about the aforementioned institute you should write the greatest place to work [...correct...] and employees are commited to the company ) is where there is trust in the management and employees commitment with the company.
Again, I'm looking for help here myself but I think I spotted some of the more grave mistakes. I cannot guarantee that I didn't make unnecessary pedantic corrections.
