I'm currently 14 and have a job on a Sunday - but, due to laws dating back decades, a child can only work for a maximum of 2 hours on a Sunday. I believe that this should be increased to the same as any other day, as in the modern day this law has no reason to exist.

All this law does is harm children trying to make some money and gain experience from working, and makes employers less likely to hire people under 16 as they can only work for a short amount of time on a Sunday.
