New Sheriff in Town

I thought I was doing a fairly decent job at my fast food job in my new role.  I was trying to do everything in my power to help grow the business.  Because of this, I was literally working almost 60 hours per week. I was there every single day for some reason or another trying to help us get better.  Well, all that hard work was appreciated by the higher ups, but the overtime they were paying me apparently became a problem.  They brought in another store manager to help me.  I'm not saying that I don't appreciate the help but some of her methods are completely opposite of what I was trying to do with the team.  Also, on a more personal note, bring on another manager meant my hours had to get cut - drastically.  I won't know until my next paycheck how much of an impact this will have financially but I can't afford to make any less money in my current situation.
