Both verbs make sense in your context, but they mean slightly different things.
Getting away implies success: like FumbleFingers said, the movie probably ends with the character still on the lam. It also implies, albeit to a lesser extent, that the cops initially had custody of the character, which he escaped.
Running away does not imply success. I don't know if I'd go so far as to say it implies failure, mind you, but I wouldn't be as hopeful about the eventual fate of a character who was running away as I would be about one who was getting away. Running away also does not imply escape: he could have started off in police custody, or he could have started off free as a bird, we don't know which.
In other contexts, these verbs may or may not be interchangeable. For example, teenagers run away from home to get away from an abusive parent, but not the other way around.
Target is organizational and technical managerial staff, and representatives thereof.
The only thing I'd change about this sentence is adding the to the beginning, in front of target, because it needs a specifier. Your use of thereof is correct, meaning the target also includes representatives of organizational and technical managerial staff. This is extremely formal diction; perhaps that's why it feels a little strange to you?
The target group consists of organizational and technical managerial staff, and their representatives.
This is just fine, and conveys the same meaning, though it is less formal. It's not informal, mind; this is perfectly acceptable language in a professional setting. Additionally, it's a little more accessible than the first sentence, precisely because it's not as rigidly formal.
or even to insert the word "respectively"?
Don't do this, because it will be confusing to the reader. Use respectively to indicate that items in two lists correspond to each other in sequential order. For example, we have meetings on Monday and Tuesday, at 1:00 and 3:00 respectively. Here, respectively tells us that Monday's meeting is at 1:00 and Tuesday's meeting is at 3:00. You don't have this kind of structure in your sentences, so you don't need respectively.
Ultimately, both of your sentences are acceptable in a business setting, so it's up to you how formal you want to sound. If you're writing a legal document (a contract or bill) or giving a speech to heads of state or other equally important people at a formal business event, the first is more appropriate. If you're writing something up for your manager and your office is a casual dress sort of place, stick to the second. Beyond that, it's your call.
Best Answer
run away or flee sounds like something that refugees do: it's not something that you would want to associate with a paradise resort.
escape is probably a good word to use about the daily routine. It suggests freedom, which is a positive idea. get away is similar.
There is a significant difference between get away and run away, as explained here
I would recommend using escape for the first clause, then something different, also with positive connotations, in the second clause.
