Hi Emilie,
The topic of the work culture in Brazil is pretty complex and depends a lot on the geographical area you're working in and the type of work.
Generally speaking São Paulo and Rio won't be very much different than what you're already used to. Other parts of the country can be a bit problematic.
Regarding the workplace, a few do's and don'ts.
1. Don't assume that since Brazilians are a kissy, huggy, touchy, feely people by nature that this carries over to the workplace. It does not. A simple handshake will do. If you do hug somebody or they hug you don't get carried away with it.
2. Don't chew gum in the workplace, it is considered the height of rudeness in most places.
3. Treat your co-workers with respect and they will in turn respect you. Give them credit for their work and let them know their contributions are important.
4. Never take credit for something that someone else has done. If your boss credits you with something by mistake, set the record straight right away. The person who really did the work won't see you as a threat, but as an ally.
5. Don't assume what's funny back home will be equally funny here. There's a vast cultural difference and your Brazilian co-workers might miss entirely the point of a joke that would have them rolling on the floor in North America. Some phrases for example just don't lend themselves to translation or lose their subtle meaning when translated.
6. Be very careful about gestures. There are some things that in North America, the UK and Europe mean one thing and something completely different here. Some have very bad, insulting meanings. For example the 'universal' OK gesture of making a closed circle with the tip of the thumb and index finger and the other three fingers raised means something VERY OFFENSIVE here in Brazil. Don't use it. I can't tell you how many times, even after knowing, I've made that mistake just out of habit. I've always been very embarrassed.
5. Small talk is very important in the workplace, especially with people you've just met and before business meetings for example. It's always a good way to break the ice. Try to stick to safe topics, unless you're really up on sports try and avoid talking about soccer (futebol), avoid politics and religion.
6. Brazilians are hyper-sensitive when it comes to criticsm, especially criticsm about the government or bureaucracy, so tread lightly. For a culture that accepts people from all over the world they oddly seem to express an attitude that, regardless of how long we've been here in Brazil, we're just visitors and we don't have a right to form or express negative opinions especially about the government and bureaucracy. They tend to take it as a personal attack.
7. Socializing with co-workers is quite common, but it is usually restricted to a quick drink or two after work. Rarely will someone invite a co-worker to their home for dinner for example. If you do get such an invitation consider yourself extremely honored and NEVER refuse. Always bring a swmall gift; a bottle of wine; flowers for the co-worker if female or for a male co-worker's wife, etc.
8. Business gifts should be nice but inexpensive. Giving a gift that is very expensive will often cause the receiver to feel you're imposing some kind of obligation or expect some favor in return; or it will just be embarrassing for him/her.
9. Brazilians are crazy for postcards, if you travel (especially back home or to some other country) make sure to bring back lots of postcards and pass them out like candy, you'll score lots of 'Brownie points' that way.
10. Being direct - While Brazilians expect and appreciate honesty in their day-to-day transactions with those around them; saying EXACTLY WHAT YOU THINK in every given situation is not always a good thing to do. If your co-worker asks what you think about an idea or a task he/she's doing and you think it's pretty lame, don't come out and say so. Try to approach your answer from a different angle like..."What do you think would happen if you did _______?" "Do you think it would be easier and more effective to _______ ?" something like that. Always try to negotiate a changed approach and leave your co-worker thinking it was his or her idea.
Hope this is helpful to you.
