The developer of "Sims 4" has disclosed that in "Sims 4 Get to Work" retail career the employees have three different skills.
According to a "Sims 4: Get to Work" SimGuru Q&A, the developer stated that the three different skills include work ethic, sales and maintenance.
The work ethic is about how employees socialize with the customer while the sales skill affects how good the employees convince the customers to buy. The maintenance skill is how quickly they restock objects or supplies and clean the store.
As the characters boost their skill, they will receive notifications about their progress or they can check the Manage Employees button in the Retail Store UI panel to see the current levels.
As for the employees quitting, the publication wrote that the employees have their own job satisfaction. If the player did not promote an employee appropriately as they raise their skills in the game, the employee will become unhappy. To check the employee current job satisfaction, click on the employee and select Check Up On X and the employee will directly tell you how they are feeling.
Furthermore, as you manage your employee, keep an eye and stay on top of what they are doing. If the employee is chatting with other employee, and likely slacking, the player needs to select Manage Employee -> Berate For Slacking.
The site added that the developer has been considered to create the "Get to Work" and EA has convinced to create it due to feedback from Sims fans and players with overwhelming support to bring the retail stores back in the game and to create a new career.
The "Sims 4 Get to Work" official website states that players can be a detective or a police, a doctor, scientist, a retail business, take pictures and learn how to bake cakes and pastries.
Meanwhile, players are allowed to have an active career each day and the player can freely swap back to a Sim home but only one career can be active per day.
