You're not working for the company, numbnuts, you're doing your dad a favor.
And learn to use proper grammar and capitalization. I suspect your dad is making you work because you tend otherwise to be a lazy slack ***.
Hi Preston, I understand: you are 17 and your brother is 15, your father owns his own company,makes you and your brother work doing manual labor and sending you both to deliver prescriptions, all for no pay. You feel: since you are not employed or insured by the company you both should not be handling these things your father has asked you to do.
There are many ways to view your dilemma and reason this out. Your father owns his own business,that's great! He is building a future for you and your brother,so, helping out in the family business is a good thing. This business will be for you and your brother one day. Showing your dad you are interested in the business may change the way he approaches you to go to work and he may start paying you. If you are uneasy about delivering these prescriptions talk to your dad about your concerns. Working for your dad (whether you know it or not) makes him proud. When you support your dad by doing what he says it makes you all more successful and closer as a family. Supporting your dad in this way lifts him up and makes his days easier.
For the insurance issue: some businesses carry insurance that covers all people coming in and out of the company. If you are in the building or driving a company car or van you are covered by the insurance on your dads whole business insurance policy. Ask your dad how that works. He will enjoy sharing the information with you. Also, ask your dad about the business, he will be elated that you even asked. I believe he will start to treat you differently. Watch and see!
Now from a business point of view: since you are not employed by the company you should not be doing these things. Request to be an employed,for a salary. Tell your dad you want a job with his company and you would like to do this in a professional manner.
But the most important thing of all is... he is your dad. He loves you and cares about your future. All parents want is the best for their children. He wants you and your brother to have the best of everything. So take it easy on your dad and do what he ask without grumbling or complaining. If you have concerns talk to your dad. He is here for that very reason to help you understand life until you can understand it on your own. Take care. =)
