In Anglo-Saxon culture (US, UK, Canada, etc) there is a concept that the company is paying for your time and therefore you need to always be busy (or APPEAR to be busy) during that time. For example, in New York I worked in a restaurant. If no customers came in, I was expected to clean out the fridge. Here it most workers/bosses would say that if there is a lull in work, there is no problem taking a break.
More emphasis on actual goals then on occupying time. More emphasis on getting the job done perfect than on being on time.
Also, expectation is that work will always be handed in late, so most workers or contracters in Argentina will underestimate delivery times with the understanding that it will be more. When I work with a US client I do the opposite: give them the worse case scenario time frame and then hand in the work early. In BsAs that wouldn´t fly: you wouldn´t get the job because people would be scared off by the estimate.
I work in the film industry, and this may be a bubble, but everyone shows up on time and takes their job very seriously. More likely to be motivated by the project or work conditions than salary--I´ve had technicians turn down "easy money" for "easy work" because they felt like it was beneath their artistic standing.
Great probelm solvers--since there is a more unstable economy, lack of imports, people here can get anything done with no resources. If they don´t have the correct tool they will find an alternative.
Of course, these are all generalizations! I could also write a longer essay on US clients and how they don´t listen to advice we give (not belieiving it) and then causing problems later on. They also tend to belittle local workers assuming that they are lazy.
