It's evident that there is no love for him from Shukla's side. He is just scared to go against him no matter what. Paras isn't even as articulate as Asim or Bagga that he's scared to fight with him. Paras will never get physical with him as he's scared of his wig. Paras doesn't have a strong fanbase and Shukla knows that. Paras is dating his ex or was dating her.
In the SR there was annoyance on Shukla's face for Paras at times but he kept it under control.
Paras and Shukla are not natural friends. Their personalities are different and they'd never be friend sunder normal circumstances.
What is Shukla getting from this?
My guess is when Paras brought out his driver's name and said that he has told him a lot about Shukla, it scared Shukla. Even Rashmi knows a few things about Shukla but he also knows things about her, so he can retaliate and keep things in check. But with Paras, Shukla's got no dirt on him and is scared that Paras will out his secrets.
