There are some managerial trainings as well, where they tell you how to ask people to do something. In many families you learn to do this by putting some kind of guilt on the other one, which people just swallow and tolerate. But it's a red flag if they have to cooperate but aren't attached to you.
They teach all other kinds of things:
* how to do a compliment. Most people do it so that it makes you feel unease. I hated when people do their "you're so great" thing (your local culture may vary, but flattery isn't doing you any service in any place). Most of advice on the internet is absolutely horrible.
* how to ask for a favor. Lots of people start this with false signs of care ("hey, how are things going?"), or flattery. This is absolutely visible on the recepient side, and irritating. It was appalling to learn I was doing this mistake. But a great learning experience.
* how to ask not to do something;
* how to solve conflicts;
* how to talk and not to talk at an interview for an employee position (like programmer);
* how to talk at an interview for a managerial position;
etc.
I can't overstate how helpful both of these were (the managerial course, and the theatrical psychology group training).
