If the premise of your business involves paying less than a liveable wage, you're not going to get a lot of sympathy from me. Also I doubt there are many franchisees with only one store...
This is Tim Horton's. Cheap coffee cheap snacks cheap sandwiches. It relies on cheap labour or else prices look like Starbucks and then people don't go to Tim Horton's.
As the business owner faced with this you have a few choices:
1. Raise prices considerably
2. Fire employees and make 15 do the work of 18
3. Cut costs (those other benefits) to make it amenable
Since #3 catches negative publicity, they will do #2. Much worse scenario having people unemployed and earnings $0 rather than employed and earning $24,000/year. Once he does that the business owner has stretched resources, will lose a bit of efficiency, but he'll be fine.
The attempt to redistribute wealth from the business owner to employees turned into the 3 fired employees' incomes now being redistributed to the other 15 remaining in effect, and they're working harder for their money.
Your analogy that, because they have multiple stores (they don't...you just made that up) and are wealthy that means they should be ok with a 30% pay cut because they're wealthy makes no sense. How about you donate $54,000/year to your local Tim Horton's and split the lost profits with the owner. You should be fine. You still make good money. Isn't socialism grand?
