This is the causative-passive form. It means someone forces you to do something, and you don't want to do it. The feeling of being made or compelled is key. For example, if your boss makes you work overtime, you say 残業させられる. It often implies a sense of suffering or inconvenience.

Construction: For Group 1 verbs (like 行く, 飲む, 話す), change the final u to an a and add される: 行く → 行かされる. A longer form, 行かせられる, is also possible but less common in speech. For Group 2 verbs (like 食べる, 見る), add させられる to the ない-form stem: 食べる → 食べさせられる. する becomes させられる, and 来る becomes 来させられる. In casual speech, the short form for Group 1 verbs is preferred, but the long form is also correct.
