It's a question of tradeoffs between professional accountability and improved working conditions in a given field, based on factors like how bad things can get in that field without accountability, how well (or poorly) employees are currently treated and paid, how likely employees are to take advantage of unaccountability, etc.

People very much care about accountability when it comes to law enforcement, because compared to regular employees in most fields they have very direct and outsized power over society. And police aren't exactly underpaid either.
