most people now work in jobs where they do one  kind  of work; they are carpenters, bankers, cooks, mechanics, and so forth. likewise, most  businesses produce  only certainkinds  of  goods  or  services, such as cars, tacos, or gardening  services. this feature of  production  is known as specialization.

doing so would not only increase your productivity potential / but also increase your productivity standards for certain jobs (e.g. data entry; secretarial work), which is a direct skill that is valuable to employers.   furthermore, if you work in a a secretarial job, this would allow you to accomplish tasks such as "touch typing" a lot faster (without sacrificing quality) —   allowing you more time to accomplish other tasks, making you more efficient and even promotable in terms of pay raise and in terms of promotable to other positions with higher earnings — and even teach new staff members.
