Svantaggi
Horrible company, they don't care about the employers, I had to get more than 20 calls per day while some people was getting 4 calls. The Portuguese language team have only 4 people to cover all hotels in Brazil and Portugal. They don't give you training that it will be useful for your work, they will expect you to learn the entire system in one week (Including fiscal rules for the different countries) and will put you in front of computer to get calls straight away with the same goals of the other members of the team who are working there for years. You will work on Christmas, New Years and bank holidays and do not expect any xmas bonus or pay raise. If you are not available to get calls, no matter why, more than one manager will slack you to be available every minute. Many managers from US will shame you sending emails for all the teams around the world, copying all the managers, asking you to be available in the phone even if you already got more than 20 calls and you are about to finish your shift. Do not expect to have a career opportunity, because it doesn't happen for employers who start working on L1 of support.
