My question involves employment and labor law for the state of: North Carolina.
I am a part-time, hourly worker. I am automatically scheduled on a monthly basis by an electronic system, based on my availability and the availability of other employees. There is also a "swap board" where people can trade or give/claim shifts. I tried to claim several shifts that another employee chose to give up, but received an automatic message saying that I cannot claim the shifts because I am at my "weekly max."
I understand that, as a part-time employee, I can't expect a guarantee to be scheduled by default at over 40 hours per week. However, I was counting on being able to claim other employees' shifts if they choose to swap them, which I was told happens frequently, and I was never told before employment that there would be a restriction against this.
I realize that this is likely a shot in the dark, but is there any kind of legal basis at all for challenging this automatic, absolute restriction? For what it's worth, I know that my superior, who is also a part-time hourly employee for the same company but at a slightly higher pay level, and who has the authority to override scheduling restrictions, frequently works over 40 hours per week.
