Send a text message asking the boss for a raise.

In fact, it's best to say it in person, that is, the boss, I come out to work to make money. I have been with you for seven years, and you should also know my interpersonal skills. As you know, the prices and expenses outside are so high, and my workload is not equal to my salary. I am alone outside the factory (distributing electricity according to equipment and material requisition), but my salary is the same as theirs (lathe, milling machine, etc.). If the boss doesn't agree, you can just resign. Now the electrician is looking for someone taller than you. Show your courage and courage. The boss eats the weak. Remember to say it in person.
