But, in a work environment, I think some people would be careful about "showing they are good at lying". Therefore, when it's their turn to be the imposter, they will self-sabotage so they don't even try to manipulate or lie. I suppose all this depends on how political or close-knit the team you are in is, so YMMV. I can see this working great in a startup, but maybe not so much in a larger company, where a certain amount of politics permeates interactions.
I think this takes a toll on how fun the game can be in the end. Which is why, I don't think I'll recommend Among Us again, because I think some people just don't want to show a "dirtier" side of themselves especially in front of others.
Side note – I do love Among Us and I am playing it with friends whenever I can. I do think it has some great team-building ideas in it, probably unintentionally, as I don't think it was created as a workplace team building game. If there could be a similar game, that would keep the team building, but with less of the deceiving, that could be a real winner for the team-building activity in the age of remote work.
I think the best analogy for this is when AOC played Among Us and was the impostor. Was she going to turn her political mind to 100% and win the game, and in front of the world show "how it's done by a pro"? I don't think so. Similarly, I think a manager or someone jockeying for a position would be reluctant to play to win, especially as impostor.
A thing to point out as mentioned way above, the issue with any traitor mechanic game is that while they can be great fun, involve a lot of exploration of social dynamics, they are also not really good at team building because they require at least some of you to lie/cheat/back-stab.
As a designated owner/bringer of several traitor mechanic board games, in the before times, I/we had a general rule that traitor mechanic were "first thing in the game night" games, and should if possible generally be followed by a true coop game (things like Hanabi or Pandemic) or a silly judge game (such as Apples-to-Apples or Action Cats), in order to avoid certain types of after-game drama, cleanse the palates a bit, and do a bit of a cooldown/after-care.
Unfortunately, traitor mechanic games are generally very easy to do remotely in a video chat while a lot of the pure coop games are "us versus the board" that are tougher to do remotely. Some of them have great videogame adaptations, but in videogame form lose some of the intimacy you'd want from a good video chat, and also often give all the information to every player at all times which only encourages the types of coop players that like to run the entire game and play everyone's turn as min-maxed as possible.
