Dina finally redeeming herself for her actions in the season 1 finale by Blackmailing Jeff into not firing Amy.
Garrett in "Black Friday." The entire day has been filled with so much carnage that the staff are at their wits end, not helped by food poisoning, and consider walking off the job. Garrett, however, is too stubborn to give up despite being a notorious slacker, and fires back at the staff with this speech:
Garrett: I don't like working here.
Amy: ...okay.
Garrett: But it's my job! I do the bare minimum. But I don't do less than that. And I'm not about to let a bunch of deal-hungry rubes trash our store, and make me feel bad for Dina! Which I did not think was possible! So I'mma get out there, and I'm gonna finish my shift. Yeah, I'm gonna cut corners. And I'm gonna phone it in. But it'll never be said that Garrett McNeill did not do just enough to not get fired.
And he wheels straight out to the first available register, retches in a shopping bag, and opens up for customers, all while triumphant funk music plays in the background.
Season 4
After seasons of Dina belittling and insulting her, Sandra gets a moment of power in "Baby Shower" when she refuses to help Dina come down from the harness, smiling smugly all the way. Dina admits she respects Sandra in that moment as much as she hates her.
"Minor Crimes." Amy finally becomes store manager... courtesy of Laurie, the district manager who intentionally tried to pass her over to install her dimwitted son as manager instead. How did Amy convince her? By Blackmailing Laurie and threatening to tell corporate about Laurie's cocaine habit. It's telling that Laurie never comes back to Amy's store ever again.
This comes up again in "Sandra's Fight" where during a meeting with corporate, Amy uses the same blackmailing on Laurie to get their rival Cloud 9 closed instead of her own store.
"Salary," when Amy finds out what she now makes a year courtesy of her new position (let's just say it's... considerably more), and then cut to Amy strutting through her store with a huge smile plastered on her face. It's nice to see things finally going Amy's way after so much in her life has gone sideways. Sadly it doesn't last, as these things rarely do for Amy.
Sandra gets one in "Easter" with Jerry's help. Jerry dressed up like an Easter bunny and walked around the store all day, just so vengeful Carol doesn't catch him fooling around with Sandra. He gets one for getting away with it, and Sandra gets one for convincing Dina that she's hallucinating and there's no bunny. Yeah, it's petty and cruel, but how often does Sandra put one over on Dina?
Season 5
"Curbside Pickup" is one for Dina. Cheyanne and Jonah are trying, but they're struggling hard to keep up with the demand of the new curbside service, even though Dina's constantly barking orders at them. Eventually Jonah gets fed up, and tells Dina she probably couldn't do better. Determined to prove them wrong, we then see Dina working at super speed, filling out six orders at once. Even after a sudden accident in the parking lot, after which she looks badly hurt, Dina proves to be a Determinator by getting back up and still attempting to finish an order! Dina's not an asshole to everyone for nothing - she just works at an insane standard.
Dina telling off her dad in "Myrtle" for a callous, hurtful comment he made, just when they seemed to have a good relationship again.
"Favoritism." Amy's trying to bend the rules to get the still-undocumented Mateo installed as her new assistant, but when accusations of, well, favoritism, start flying around (which isn't exactly wrong), she stages some fake try-outs for other interested employees, just for appearances. You'd think including Marcus, one of the store's resident boneheads, in these try-outs would be pretty generous... except Marcus inadvertently throws a wrench into their plans, as he displays incredible Hidden Depths by using his experience as the warehouse manager to completely ace the try-outs and make Mateo look like a chump. Turns out that bonehead is actually really good at his job.
Bonus, smaller moment of awesome - Marcus has been living with Mateo's mother long enough that he can now keep up with Mateo in an argument in Tagalog. Holy shit, Marcus!
Sandra also gets one in "Favoritism" after a dispute over a stock display turns into a power struggle between Dina and Glenn, with her caught in the middle. Having taken all she can of their bickering, she locks them both in the electrical goods storage cage, furiously telling them she's had enough of them and they can come out when they have sorted it out between themselves (and she's not fooled later by their clumsy attempt to pretend they have). They're still in there by the episode's end.
Dina quickly foils Carol's plan to kill Sandra's cat by distracting Carol and punching her in the stomach, then snatching the cat and running.
"California, Part 1." Realizing that all the other prospects for the big job opening at Zephra are Latinas, Amy goes into the interview giving them them the Latina they obviously want, before she gets fed up, refuses to play along, and demands that she be judged on her own merits rather than a cheap diversity hire.
Amy: I'm qualified for this job because I have 17 years of experience and I know everything there is to know about our customers. But if all you're looking for is someone with a spicy last name, then I suggest you keep looking.
Back at the store, Amy assumes that her big opportunity was probably blown over her making a point... until in the middle of a conversation with Jonah, she receives a call from Zephra, telling her she got the job, and she's going to California for the biggest promotion of her life. After five seasons of Amy's life falling apart and slowly being put back together, it's pretty satisfying to see it all pay off.
Season 6
"Floor Supervisor" is Cheyanne's big moment. In a petty effort to prevent Jonah from becoming floor supervisor, and having to put up with being challenged by him, Dina talks Cheyanne into throwing her hat into the ring, and then gets the entire staff to rally behind Cheyanne for promises she can't keep, plus slandering Jonah on top of that. Being The Ditz, Cheyanne doesn't clue into the fact that Dina's just using her for a while, but the moment she does, Cheyanne goes off on Dina in front of the whole staff, pitching her ideas for the store and calling out those who didn't believe in her. And then she becomes floor supervisor anyway, off the strength of her own advocacy for herself. Get it, girl!
"Hair Care Products," and Garrett's Rage Breaking Point. He spends the whole episode watching virtually all his coworkers incompetently dealing with systemic racism, and then Glenn makes it much worse by giving all the black employees "reparations pizza"(?), and then he even fumbles that plan with Insane Troll Logic. Garrett finally gets fed up with the core message of being actively anti-racist being diluted and with all the pressure being put on him to assuage Glenn's white guilt, so Garrett picks up a store phone and unleashes a verbal flamethrower.
Glenn: For you the pizzas are reparations for racism. And for the white employees, they're reparations for not getting pizza! Garrett: Okay, so it's an All Lives Matter pizza party? Fine. Great. Okay. That's perfect. [picks up the phone and pages the store] Attention, all Cloud 9 employees in all departments. Please report to the break room for pizza! Because apparently now? Everyone gets pizza! Never mind that the basic infrastructure of this country makes it so that one group of people gets way more pizza than the others, or that some of us spent over four hundred years forcibly making pizza for white people! [slams down the phone]
Bonus points for letting Dina have it for putting some of that pressure on him.
Extra bonus points since on his way out of the store that night, he throws the cardboard cutout of Cloud 9's culturally appropriative mascot in the box crusher.
