How the Tables Turned

I was the company's marketing director, but my salary had always been only sixteen hundred dollars. One day, Timmy Sunderland from finance accidentally sent the payroll spreadsheet to me by mistake. On it, I saw the lines: Technical Director–10,000 dollars. Marketing Assistant–5,600 dollars. Receptionist–2,000 dollars. It also clearly stated that my salary was ten thousand, but most of it had been deducted and given to Timmy! Only then did I realize that after a decade of service at this company, they still treated me worse than everyone else. I rushed into the office belonging to my boss, Jessica White. "I want an explanation." She said to me, "This is a business decision, and I'm not at liberty to explain anything to you. Haven't you always been the one who understood me the best?" Because I had feelings for Jessica, I gave in. A few days later, when the holiday arrived, I did not rest. I went out to negotiate an investment of five million for the company. I treated the client to dinner and drank with him until I suffered internal bleeding. When I took the receipt of 2,000 dollars to Timmy for reimbursement, he transferred only 100 dollars to me and even said I was just trying to take advantage of the company. Jessica also scolded me to my face. "Only incapable people need to spend that much on clients. Timmy's right, you're just trying to take advantage of the company." This time, I decided not to endure it any longer. In anger, I quit and joined another company. The first project that I was put in charge of was worth over ten million, and Jessica's company was the investment target…
