Hourly job so depends on times you get selected. And there slow times of the day for sales

Pros

Some customers are great to work with, and the role can help you build basic retail sales experience.

Cons

This review is based on my experience working under the same franchise owner connected to multiple GNC locations, including Turlock, Modesto, Riverbank, Lodi, Oakland, Sonora, Livermore, and Manteca. In my experience, the pay practices were completely unacceptable. Overtime was not paid, period. Even when employees worked overtime, they were not compensated for those overtime hours. On top of that, tax withholding was not handled properly, which led to serious issues at the end of the year. Employees should not have to fight to be paid correctly or deal with payroll problems that affect their taxes. The training and management structure were also very poor. Employees were often left to figure things out on their own while still being pressured to hit sales numbers and push certain products. Commission earnings could also be taken away if specific sales expectations were not met, which made the compensation feel unreliable and unfair. Cleanliness standards were another major concern. Employees were expected to serve food and drink items to customers using dispensers, water, and ice machines that were absolutely grotesque and would never be cleaned. In my experience, the drink dispensers, unfiltered water, and dirty ice machines were not maintained anywhere near an acceptable standard. I did not feel comfortable serving customers from equipment in that condition. Overall, I would not recommend working for this franchise. The combination of unpaid overtime, payroll and tax issues, poor management, inadequate training, unreliable commission structure, and extremely concerning cleanliness standards made this a very negative work experience.
