all based on the contract where you work and the division you work in

Depends on specific department and specific contract.

But generally speaking, for more recent contracts, up to but never more than a dollar more than a topped-out employee.  For a few years I was making only $.65 less than my manager.

They get better insurance, guaranteed full time and less hassle about overtime, and a couple other perks, though.

It's almost never worth it since the increased responsibility is completely and entirely disconnected from actual power, tools, and ...reality.

You still can't do anything about anything, but now it's your fault, and specifically your fault, and the ast/store manager is threatening you about it.  And might follow through.

A lot of managers/leads without an inside path upwards (promotion is dependent on either nepotism, desperation, or talent/skill in that order) end up stepping down or out because $.65-1.00 pay isn't worth $5 of stress.

Plus Del Taco doesn't really pay much less.  Teenagers at Target make tremendously more but probably don't get any hours or benefits.

How does it work at a certain company that defines themself as winning?

Starting pay at Kroger is kinda funny here in Colorado. At the non-union stores in the northern half of the state, it recently went up to $14 to try to get people in the door. It's still not quite as much as Walmart is offering, but it's something. But for some reason our union declined that $14 offer, so their employees (southern half of the state, plus meat/deli workers in the north) are still starting out at $12.xx. I've been topped out for years so it hardly applies, but damn do I feel sorry for union workers.

Our union's going into negotiations for this new contract asking for a $6 raise across the board. We'll see how much of that they get us. I follow them on IG, and those people still think we're in a deadly pandemic and need hazard pay, complain about people not wearing masks, etc. They show back rooms with trash piled high in front of doors and think it's corporate policy to blame rather (mocking the commercial, "safety standards lower than low low low") than the people who work there not having the two brain cells required to take the initiative and organize. What a bunch of morons to be represented by.
