I think normally you would let the null hypothesis be μ = 6.5 and then you’re alternative would be greater than 6.5

And because it's so high I can reject the null?
Just logically I know the answer is population mean is significantly less (ie employment at our company is statistically higher than average) but I need to prove it with the above I think

The null hypothesis should be mu = 6.5

The critical value for this test at almost every significance level you'd care to use would lead to a reject Ho here.

You have sufficient evidence to suggest that the mean number of years of service is higher at your company.
