After finding profits to be slightly lower than usual at the Krusty Krab, Mr. Krabs decides to start deducting his employee's pay for doing ridiculous things including talking, chewing, breathing, lollygagging, and even existing. Squidward finds this to be outrageously unfair, and he convinces SpongeBob that they should go on strike. SpongeBob, initially not knowing what it means to go on strike, is devastated when he is fired. Squidward, however, assures him that he will have his job back "and more."
Squidward starts them off by making a sign stating "Krusty Krab Unfair," but SpongeBob writes his as "Krusty Krab Funfair," making the restaurant more popular. Squidward then has SpongeBob memorize derogatory slogans about Mr. Krabs and the restaurant, though their meaning flies over SpongeBob's head. He draws the attention of an eager young teenager who thinks of SpongeBob as a living legend. Rather than join him in the strike, however, he heads inside to take SpongeBob's job.
Squidward then attempts to give a speech to the people of Bikini Bottom, who grow so excited by his words that they build up an appetite and rush over him to eat at the Krusty Krab. Mr. Krabs steps outside to taunt him about how beneficial the strike has been for his bottom line. Standing up for Squidward, SpongeBob turns against Mr. Krabs and tells him that they will stay on strike forever until their demands are met. The word "forever" strikes a nerve with Squidward, who grows deeply unsettled at the thought of being on a never-ending strike with SpongeBob.
Unable to sleep with this thought, Squidward runs to the door to beg Mr. Krabs for his job back. Opening it, he's surprised to find Mr. Krabs, who begs him and SpongeBob to return, saying that he cannot stand the teenagers he hired as replacements and that he is nothing without them. As they walk to the Krusty Krab together, Squidward relishes how the tables have turned and begins discussing the terms of their return with Mr. Krabs.
Meanwhile, SpongeBob has taken the words of Squidward's speech to heart and spends the night dismantling the establishment that is the Krusty Krab. Squidward and Mr. Krabs soon arrive, having come to an agreement. Squidward is horrified to see the Krusty Krab in shambles, SpongeBob standing proudly among the wreckage. When Mr. Krabs discovers his restaurant completely destroyed, he falls to pieces and remarks that in order to pay for the damages, Squidward and SpongeBob will work for him forever. SpongeBob jumps for joy while Squidward once more takes in the full meaning of "forever."
One eternity later, they are nothing but a skeleton crew, still working at the Krusty Krab.
The bill that Squidward gets means he has to pay twenty-one dollars.
It is revealed that Mr. Krabs keeps his dry cleaning in envelopes.
In real life, the employees would not get fired if they went on strike because it is illegal to hire new workers if other employees are on strike.
Mr. Krabs is making his employees pay for breathing, yet in the episode "Pressure," when Sandy thinks land creatures are better than sea creatures, he says it is free. However, he may have started charging his customers and employees for that at some point between "Pressure" and this episode.
SpongeBob has said he loved the Krusty Krab many times so it is unknown how he destroyed it without showing regret.
Whenever there is a crowd going to the Krusty Krab, they run over Squidward.
Every time Squidward hears the word 'Forever' from SpongeBob, he is in shock, and the word echoes in his head.
Sandals yelling "Let's go get a Krabby Patty or Let's go to the Fun Fair."
When the word 'forever' echoed in Squidward's head, it became a YouTube meme.
This episode explains why Squidward has never moved on and gotten any higher career in his life, since he has now been forced to work for Krabs forever.
This episode has the longest time period on a time card to date, "One Eternity Later."
SpongeBob says "Oh, and here's an extra fifty cents for when I was tying my shoe." meaning this episode takes place after "Your Shoe's Untied."
Squidward and Mr. Krabs are in their day clothes when they enter the destroyed Krusty Krab, but when they left Squidward's house, they were wearing their pajamas.
During the part where Squidward imagines himself as an old man, when it begins his sign reads "Krusty Still Unfair," but when SpongeBob starts orbiting around Squidward, it reads "Krabs Still Unfair."
It could've been on the other side of the sign.
In part of this episode, it shows Squidward and SpongeBob really old on strike. Yet at that age, Mr. Krabs would most likely be dead.
SpongeBob and Squidward are invertebrates, and therefore would have no skeletons to rot away to.
In the previous two episodes ("Nature Pants," and "Patty Hype") and in a more recent episode ("As Seen on TV"), SpongeBob willingly quits his job and throws his hat down. However, in this episode, he says that the hat is his "friend" and cannot bear to discard it.
When Squidward said "and more," SpongeBob only had one tooth for that scene.
In the scene where SpongeBob and Squidward were outside the Krusty Krab after getting fired, they were still wearing their work hats.
When SpongeBob runs to the Krusty Krab to "dismantle the establishment," the sky looks like dawn is breaking. When he goes inside, it looks like nighttime again.
When SpongeBob refuses Mr. Krabs' pay check, Mr. Krabs backs away even though it was really a bill.
