Enter Holo House and visit the bulletin board to the southeast. This board gives you basic information on the Workers minigame by choosing the Read option. To recruit a worker, select the Hire option. Here, you can send out an advertisement that generates 6 random workers whose quality is based on your Manager rank. Pick one and they'll be added to the pen to the east of the bulletin board. The worker will then spend their Stamina over time to generate Holocoins based on their Efficiency. When their Stamina is drained, they need to be fed fish or crops from the other 2 Holo House minigames. This also improves their level, which improves their stats, which improves money gain.

Recruiting itself costs nothing, but sending out the advertisement that generates the 6 random workers costs ((x+1)*500), where x is the number of workers you currently have hired. If you do not like your options, you can spend the advertisement cost again to reroll.
This means a worker can cost 500 to 5000 Holocoins

You can have up to 10 workers at a time.

The first worker in the advertisement list is always the fan of the Holomem you are currently playing as. SSRBs are out of luck... for now. The rest of the list is random.

Raise your Manager Level by leveling up workers. Each Manager level unlocks a new quality of workers. At level 1, you start with Bronze rarity workers, at 2, Silver, 3, Gold, and 4, the max Manager Level, Platinum workers show up, they have the highest stats.

Max Level, usually, I'll talk about stats down below.

A few months ago, the Holocure twitter sent out a link to a Google form allowing players to put in their name and what kind of fan they are. These were then filtered and then added to the game. It's likely that this form would be double checked and the in-game list updated over time, but I don't know for sure and I don't know if this opportunity will arise again.

If you open holocure.exe in notepad or similar, you can CTRL+F to find the name you put in. It will be there in plain text. But please, for the love of god, don't touch anything in the file or you risk breaking the game.

They are not. Stats are randomly set as much as the names are randomly set.

You can rename fans at your own leisure.

For hiring, workers have 4 stats.
> Efficiency : How many Holocoins the worker generates each time they generate Holocoins
> Max Stamina : How long the worker can work without needing food, also determines how much Stamina is recovered by food
> Max Level : Their maximum possible level. Level goes up by feeding food, higher tier food provides more EXP. Every level translates to 1 Efficiency and 2 Stamina
> EXP Rate : A multiplier of EXP gained when feeding food.

For hiring, I've seen up to 10 Efficiency, 85 Max Stamina, 50 Max Level, and 1.5 EXP Rate. (Thanks to xBleacheDxSungasMx for EXP Rate cap)

Compare (Efficiency+MaxLevel) and (MaxStamina+2*MaxLevel). A worker with 4 Efficiency and 50 Max Level will end up with less Efficiency than a Worker with 10 Efficiency 45 Max Level.

iunno, I've counted 8 seconds and 4 seconds, then stopped counting, it may be random. I'm willing to take more information regarding this.

Unknown, possibly infinite, or whatever how many bits that value is assigned.

Around 20 seconds, if not exactly.

20% of Max Stamina, doesn't matter what kind of food it is. It can be a Shark or a piece of Wheat.

It's random from a list of accepted food based on the Worker's quality. A Bronze Worker will only request Shrimp, Clownfish, Tuna, Wheat, Tomato, and Potato. A Platinum Worker will request every kind of crop and every kind of fish EXCEPT shiny fish and Axolotls, so try to keep an even amount of everything.
When a Worker levels up, their desired food changes. When a Worker is at max level, they'll never change their desired food.

Exact numbers unknown, but higher tier food provides more EXP. A Shrimp will get dominated by a Shark, even though they restore the same amount of Stamina. Lucky Shrimp...

When you level up a Worker, they give (9+7x) Manager EXP, where x is the Worker's level before leveling up. This means higher level workers will provide more Manager EXP when they level up. (Thanks to xBleacheDxSungasMx for this information)

You can give as much food as it takes to fill up both their Stamina and their EXP. Any "overEXP" will bleed into the next level. If you have tons of resources, feel free to be wasteful for faster levels.

Start with getting Workers with high EXP Rates and a half decent Max Level. You get Manager EXP every time they level based on their level, and higher EXP Rates let you get more levels faster. When a Worker hits their max level, retire them for a new one, and repeat until Manager Level 4. (Thanks to xBleacheDxSungasMx for this strategy)

You could minmax and reroll a bunch to try to get the perfect Worker, but it's not worth it. I chose to pick up Workers whose Max Level is at least 45. Not all Platinums will get that high, not all Platinums will even reach 30!

It's easy for the Stamina restored of a food to grossly overpower the value of that food being sold. Even if 1 stamina = 2 ticks of Holocoins, a 50 Efficiency Worker would generate 100 holocoins per Stamina, if that worker has 150 Stamina, then
Let's say a Worker has 150 Max Stamina and 50 Efficiency. Any fish would give 30 Stamina. If we assume 1 Stamina is enough for 2 ticks of Holocoins, which means that 30 Stamina would become 3000 Holocoins. If it were a Shark, we just multiplied it's value by 4!
Of course, this is over the course of 10 minutes.

Any time the game is running. You could be playing the proper hoard mode, or grinding for fish, or AFKing in the house. This is the power of Workers, even if it takes a while to get them up to max speed.

10 reasonably-maxed workers can generate 250K+ coins while you're off on a Stage. I'd love to post a screenshot proving this, but I'll need to actually max out my workers. Right now, they're around level 20 each and generating around 140K+ after a 20 minute stage. It's nothing compared to IRYSes making 1.6M+ in 35 minutes, but you can do that while getting the extra money from Workers!
Just be sure to check up on them between each game for feeding, and don't neglect Farming or Fishing!

Honestly, I haven't decided. Kronii is hot, Ina is comfy, FUWAMOCO is wholesome, Fauna plays great games, Botan is skilled at games, Nerissa is nopan, and Sana is Eternal. But for the purposes of this game, my favorite character is Roboco, as she's all about leveling up and level scaling. She also has a nice outfit and design. You know why.

A Robosa named Tesladonna, mai waifu from a far inferior game. I spend half a mil trying to find the name to no avail...
