The profession system in ArcheAge looks complex, currently there are 21 professions/jobs, which we can split into different categories like: gathering, crafting and other.
Each character has a certain number of "labor power points" or just "labor" in short, that are similar to an energy bar (located on top of the experience bar).
By collecting, mining, manufacturing and processing materials these points are being used up until they are exhausted, and when they reach 0 points, your character will be unable to perform any of the activities listed before.
Labor points regenerate automatically. Five labor are restored every 5 minutes. This results in a maximum of 1440 labor per day. There are also object which can boost up labor points a bit, such as the bad bed (from season Update 1). Maximum a player can currently collect 5000 labor per account, it can be divided among the characters there by free choice.
The maximum amount of labor is determined by the level of the player's character and his accumulated experience in all professions.

Profession levels by points:
0-10.000 -> Novice
10.000-20.000 -> Apprentice
20.000-30.000 -> Journeyman?
30.000-40.000 -> Expert
40.000-50.000 -> Master
Leveling up process for professions:
In order to get a profession to the next level, first you need to reach 10k points with the given profession, then two arrows will appear next to its name (look at the picture above, arrows down/up at nb 7.), clicking on the up arrow you take the profession to the next level, this applies up until the last level "Expert".
From the total of 21 professions, you can level up 5 to Apprentice level, from which 4 can be Journeyman level, from which 3 can be Expert level, and from which you can level up 2 to be Master level, per character.
Why do i need to level up professions?
When you have a profession on higher level, the labor consumption is less for the activities within that profession. In some cases new recipes will open up, to collect/mine certain resources a higher level of profession is needed, to craft certain things a higher level of profession is needed, to use certain items a higher level is needed as well. Also in case of gathering you have better chance of getting rare resources, in case of crafting you have a better chance to craft more rarer items. And there are some other perks as well.
