I major in home appliances, but I don’t have an electrician’s certificate. I want to work as a general maintenance worker in a hotel, but I don’t know what I will do.

Hotel general maintenance workers are actually similar to plumbers and are responsible for the maintenance of the hotel's water supply and power supply, as well as the maintenance of computer networks and telephones. Maintenance of elevators and air conditioning is also included. In other words, you must know how to replace water fixtures such as faucets, simple installation and maintenance of daily lighting, maintenance of computer network cables and telephone lines, and maintenance of elevators and air conditioners. Specific tasks vary depending on hotel facilities or job categories.
