This question has surely been asked by many unemployed at some point. It is usually thought. The unemployed person may choose to take an examination to find a new job opportunity. However, both options can occur together. One can prepare an opposition and at the same time continue with the active search for work. One thing does not have to be incompatible with another.
On the other hand, on the subject of oppositions, there is not a good moment right now. The offer of public employment is decreasing every year with what every time fewer places are called to work in the Public Administration. This means that there are fewer places and more people show up than ever due to the increase in the number of unemployed, many of them at university level. That is to say, now it is much more complicated to get an opposition than a few years ago because there are fewer places and greater competition.
The great advantage of getting an opposition is that you get a permanent job for life. This is the main motivation. Due to this issue, there are still unemployed who continue to bet on the oppositions even at this time that everything has turned against them. The final prize is very succulent, but very few (less and less) get it. Therefore, you have to seriously consider whether it deserves so much effort and then you have few options to achieve it.
The decision will depend on each one. But it will not be easy at all in any case. Which one would you choose?
