Edison hired Tesla to work for his company Edison Machine Works. Tesla's work for Edison began with simple electrical engineering and quickly progressed to solving the company's most difficult problems. Tesla was offered the task of a complete redesign of the Edison company's direct current generators. During his employment, Edison offered Tesla $50,000 (equivalent to about $1 million today, adjusted for inflation)[25] if he redesigned Edison's inefficient motor and generators, an improvement in both service and economy.[20]:54-57 Tesla said he worked night and day to redesign them and gave the Edison company several profitable new patents in the process. During the year of 1885, when Tesla inquired about the payment on the work, Edison replied to him, "Tesla, you don't understand our American humor," and reneged on his promise.[26][27] Tesla resigned when he was refused a raise to $25 per week. At Tesla's salary of $18 per week, the bonus would have amounted to over 53 years pay, and the amount was equal to the initial capital of the company.[28] Tesla eventually found himself digging ditches for a short period of time ? ironically for the Edison company.
Edison was a cocksucker who took advantage of people.
