Best practice
Use "had worked before" to clearly establish a sequence of events in the past, emphasizing that one action preceded another. For example, "She had worked before as a cashier, so she was comfortable handling money."
Common error
Avoid using "had worked before" when a simple past tense would suffice. Overusing the past perfect can make your writing sound stilted. For instance, instead of saying "He had worked before and then he applied for the manager position", consider "He worked previously and then applied for the manager position."
