Best practice

Use "had worked on" to clearly indicate that an action was completed before another point in the past. This helps to establish a timeline and avoid ambiguity.

Common error

Avoid using "worked on" when "had worked on" is required to establish the correct past perfect tense. For example, instead of saying "I worked on the project before I left the company", say "I "had worked on" the project before I left the company" to show that the work was completed before the departure.
