Sometimes you have an employee that is so good at their job you never want to replace them
If you promote him then he’s just going to take the title and leave for more money.
No virgin lieutenants allowed in Starfleet
He didn’t commit enough war crimes (lacks leadership mindset)
He put cream into the Captain’s coffee once and she never forgave him.
COFFEE. BLACK.
No one under him is qualified for bridge crew. Every single person not named in the credits on Voyager is completely incompetent. Promote Kim and you have to promote crewman Bushnell who thinks Warp drive opens a portal to hell everytime, smells awful and calls all women “females”.
He must have learned warp theory from lt. broccoli
They needed to keep at least ONE ensign around, and all the others got promoted or died.
Because he was an experimental ensign.
Starfleet had deliberately trained him wrong, as a joke.
Does that make Boimler the control ensign?
The promotion pip was continuously traded for coffee rations
His first name isn’t really Harry, it’s Hitler. Once Starfleet learned the truth, it realized it could never promote him for fear the secret would come out.
Janeway actually did try to promote him, but he overslept and missed the promotion ceremony.
Because of legal complications of being from a duplicate voyager post “Deadlock” he couldn’t be promoted further than ensign.
Tom told Janeway it’d be funny if the EMH out ranked him while giving her a fresh pot of coffee.
At the bar celebrating his new commission aboard Voyager he met an ensign named Mariner.
He secretly works for Starfleet’s Internal Affairs and uses his position to spy on Janeway et al.
Its the Star Trek we need.

More likely he’s one of those temporal cops. He brainwashed Janeway to downplay the causality problems from the final season because he couldn’t let her say what really happened.
