Work Scenario

I have a work situation that I'm concerned about.
The boss decided to make a work schedule, without consulting any of the workers.
When the co-workers and I saw it, some of us were concerned while some didn't care.
I didn't care.
My talkative co-worker did.

She wanted Saturdays off, because it was her only time to spend time with her family (or was it her boyfriend?).
She also lost several hours, which she needs since she depends on her salary.

I, on the other hand, received a great boost in hours, and got Saturdays and Sundays off.
The boss even tells the other co-workers, that I am the best and most capable employee he has.

The only reason I am getting treated so well, is because the boss likes me.
Not that I don't like the idea of being favored, but it is also comes from the boss being quite sexist towards females.
Some of the co-workers asked me to confront the boss and switch my day off with hers, which I decided to do so since I can deal with working on Saturdays.
I told them that I could do BJJ if I took Thursdays off instead, so it kind of worked out.
I left out the part that I could be going fishing and taking day trips if I had Saturdays off, but I didn't see it as that much of a deal.
And yeah, the boss was surprised that asked him for the switch (which is a normal reaction), but he did it.

But then today, the boss kicked her out of the store because she wasn't wearing the 'right work clothing'.
And she just left quietly, with a glare that was leaking with her frustration.

What do I do?
I could take the easy way out, and ignore it while enjoying my royal treatment at LaBoulangerie.

Or the path that I'm closest to achieve, which is trying to mediate the tension around the work force.

Or maybe, I should confront the boss directly, and telling him that he is being unfair.

Or.... this could be the most fun, setting up a secret group with the chef downstairs (she's a mother with 6 years of business experience) and create plans for a better workplace.

Well, I'm not sure what I will be deciding on, but I'm currently on the mediation path.
The only thing is that I will be a bit too passive, and the problems will not likely dissolve.

Also, my talkative co-worker may decide to quit because of how she is being treated at work.
She's also quite confrontational, so it obviously works against her when.... oh, both the boss and his wife don't like her.
And today, I started a good first conversation with the boss's wife.
Meaning that both the boss and his wife likes me, while they are displeased with everybody else.
I'm starting to think that I may be a bit too manipulative.

Also, my talkative co-worker is actually really nice.
She's the one that taught me how to do everything, in a really well-mannered way.
We have the best sync during busy hours, and is much more capable than me.

But I am scared, because I decided to reveal that I am a Christian this week, and she doesn't seem like that.
She's been quiet around me, and changes from talking to whispering when I am around.
I dunno, maybe she's just having a hard time.
And maybe she's having her period right now, she's mentioned stomach cramps yesterday.

But what if she interprets the current situation, as a suck-up that's stealing her hours, forcing her to find another part-time job?
And maybe she's accusing me of things behind my back?
And maybe I am trying too hard to get people in my work environment to like me?

Maybe, I should be praying before making decisions.
