How about atm maintenance?

ATM maintenance has no future, and it is suitable for secondary school students who are waiting to die to play games and watch movies.

The company is too mobile to recruit fresh graduates with no social experience (secondary technical school students with no self-motivated third-rate schools in the mainland). The trick of the company is to deduct the money for three years and sign a three-year contract. After three years, your professional skills are useless, and you dare not ask your boss for a raise or jump ship.

You studied all your life until you were 60. It's not as fast as a factory worker's job-hopping promotion and salary increase! Veterans in this industry do fake work orders every day and reimburse fake fares.
