Off the top of my head I can think of... Fire someone and let someone go He didn’t know how to do his job so they fired him He didn’t know how to do his job so they let him go If you want a more idiomatic expression I guess the only one I can think of is “give someone the boot”. For example, “I didn’t do well at my other job so they gave me the boot” Let’s see what others have to say

I'm not super grammatically knowledgeable but I can tell you that conversely to me sounds like you're going to talk about something opposite. While saying on the contrary kind of has an argumentative tone to it, as if you're going to give a rebuttal or something.

In the end, there's such a small difference that even us native speakers who don't study our own language's grammar don't know, so don't worry about it too much.

But I do agree with Patrick, at least for normal everyday conversations you'll likely never hear someone say "conversely".

Public relations

No, advance in this case means ahead of time. The only time people get advance notices of termination are usually for things like mass unemployment for example, a company going out of business. Otherwise a notice of termination is on the spot you getting fired.

I honestly don't understand why people say it either, but I'm not the one who creates the hip lingo these days. Ghost means to completely ignore, you don't ghost someone then go back to being their friend afterwards. I mean maybe, depending on the circumstances of the situation. You can use urbandictionary.com if you want to find the definitions for slang words, most words are pretty accurate in their definitions.

My English speaking English level is low, my listening level is also poor, but my level of reading comprehension is acceptable but I want to improve my skills in this area, however I have never have read a book in English, I have only read news on the internet, that's why I want to start reading books in this language, I already have some books that I bought some time ago and that I have not read. They are books with a simple argument but I want to increase the degree of difficulty little by little. I think this methode method of study will help me to increase my vocabulary and gradually I will be able to express my self myself better.

Since its crew, it should be the "people that serve". "In the way" sounds pretty strange. I'll assume you're trying to say "down the aisle". So... the definition would be something like "Cabin crew: the people who serve customers on airplanes, trains and ships down the aisle". I've changed "of" to "on" because it just sounds slightly weird, I don't think it's grammatically incorrect, but it definitely does sounds strange, apart from the fact that saying "customers of airplanes, trains, and ships" could mean people who buy airplanes, trains, and ships.
