what walmart?

No, actually asking for less hours is not an unreasonable thing to do. Know your options, don't assume anything. Think of it this way: between college and a full time shift, you will be less productive. This means you will likely get less sleep, become more irritable, not be as happy and overall, become less productive. From schools perspective, your grades will likely drop if you don't change the situation soon. And from works perspective, this means you will be a less efficient employee. It also means your customer service abilities will lower. I would strongly advise you to pull your supervisor off to the side and explain your situation. Companies want their employees to be happy and (most) of the managers I have had have been really awesome, understanding, accommodating people. Especially with the union breathing down their neck :P

Of course, chances are if they are working you that hard then they are likely understaffed, so they may no be SUPER flexible. But in all fairness, falling into the "new employee looking bad" category is more along the lines of consistent tardiness, constantly messing up and showing little to no signs of improvement, mouthing off to your supervisor, etc. Believe me, asking for less hours does not place you in that category. If anything, if you explain how much your situation is negatively affecting your energy and well being, you would be more in the right to ask. It's not like they can fire you or write you up for that anyway :P

When it comes right down to it, your main priority is your personal health and school. The job should come second (unless you plan on working for Walmart as a lifelong career, which I seriously doubt you plan on doing, especially with a criminal justice major :P). If you don't change the situation, it will continue to negatively affect your health and mental well being (and even increase for that matter). You have absolutely nothing to lose and everything to gain by asking for less hours. Just keep in mind that you and your well being is exceedingly more important then your job.

Definitely not a bad idea to ask for less hours. Companies understand that college students have more responsibilities to work with than being at work. So I believe you should ask for less. I had to do that for my first job because the hours were affecting my grades at school. You will find the happy medium. c: I still can't and I'm not in college anymore. A lot of things have fallen to the wayside for a while now because my job dictates over my life basically. But I believe you'll do fine with finding what you need to do in order to be happy with having time to yourself, making money, and keeping up with college.

c: You are always the first priority over anything else.
