回答: "行きません" is a polite form of "行かない". i use "行きません" when i talk to my boss in the office and use "行かない" to my friends or family. "働く" is present tense and most simple expression. and if you say "1時間だけ働く" i feel you are telling the fact objectively just like a scientific report. "行きます" is also a present tense and polite form of " 行く". "行きます" is more casual and polite than "行く" so i recommend "行きます" in daily conversation.
