Employer not compensating staff for extra time

Q: I work as a manager for a Muslim man who at times stretches the time of his employees if it gets busy or is attending to personal work. He does not compensate them for extra time, and when the topic is brought up, he angrily dismisses it and says, "You are just standing doing nothing, so it’s not work." But I feel as long as they are in the shop, they are working, as they are not free to do as they like. What should I do ?

Advising a neighbour who abuses a cat

Q: My neighbor brought a cat from somewhere. But they did not feed the cat properly. So my mother gives food to the cat. The children of the family abuses the cat to the point that the cat may die any time if it stays in that house. So can I take the cat from them and give it to someone else without their permission? They throw the cat here and there and hold it by its neck. The cat will not survive if kept with them.

Father assisting one son financially

Q: Should a parent be equal to all of their children in terms of finance and gifts? 

For example: There are 4 brothers. No. 1 is a doctor, set up by the father but paid back. No. 2 is in the business with his father as a partner, also paid back. No. 3 is still studying. No. 4 is an aalim and recently started working in the business. The father wants to set no. 4 up eventually. 

Question: Will it be fair if the father sets up no. 4 in the business, without paying back. Basically giving him a business and not giving any other brother the same.
