Vantaggi
Vacation can be taken relatively freely by foreigners (even if management sends company-wide emails constantly complaining about the fact that anyone would deign to take any vacation whatsoever). They won't mess around with your work visa. If you're really gung-ho about translation or proofreading, you'll certainly have plenty to do.
Svantaggi
Fines are imposed for pretty much every action imaginable. One minute late? That'll be a fine of one hour's salary, since they'll force you to apply for that "time off" (and one minute is rounded up to an hour!). Refuse to apply for that "time off" since it's almost definitely illegal for them to deduct such a disproportionate amount of your salary? That'll be a fine of three hours' salary. Fines are imposed for forgetting to swipe your time card (or, in a more likely scenario, because the time clock is ridiculously fickle and didn't properly record your input), for writing the wrong customer address on an envelope (if you're in sales), for not filling out some obscure online form on the company website even if you've done everything right in person, or for doing or not doing something they haven't even told you about yet. The entire operation seems to be set up to give employees as little of their salary as humanly possible. All overtime work is unpaid regardless of the amount of time one puts in (oh, if an employee works 40 hours of overtime in a single month, they'll give the "lucky" soul one vacation day, in what might very well be the worst deal in history. But management really hopes you'll strive for this instead of taking your legally mandated vacation!) Want to quit this place because it makes the City of Dis look like Disney World? You'll be forced to forfeit some ungodly portion of your salary and give 2 months' notice lest they try to take even more of your money. You can also kiss all of your unpaid monthly bonuses goodbye (which can be a substantial sum, since they're only paid out two or three times a year). Company-wide emails are constantly sent that range from the absurd to the absolutely terrifying, such as a prohibition on listening to headphones (which has, thankfully, not yet been enforced, because one would actually be driven to suicide if one had to do such monotonous work in complete silence), the aforementioned gripes about vacation days, encouraging people to work harder and longer for less money, and constant threats of fines, punishment, and retaliation for mistakes as innocent as forgetting to turn off your mini desk light when you go home at 2 AM (the poor assigners...). You will find yourself buried in rote and meaningless paperwork that seems like an absurd waste of company resources (why force translators/proofreaders to send 'daily reports' on what work they've done when it's easy for management to pull the case codes and number of words they've worked on from the centralized system?) The office has a cleanliness problem, probably because the company wants everyone to consume breakfast, lunch, and dinner (and midnight snacks!) within arm's length of their work computers, leading to a rat infestation. Turnover is--rightfully--enormous, leading you to ponder your own exit every time they tell you to delete a former coworker's email address. Because no one would want to work here for long, translation quality suffers, meaning you won't be proud of the work you produce if you work at the speed they require. The company seems to get away with poor quality quite often because their customers often don't speak the target language.
