The Mexican has faced the wrath of some leading stars this year - including Kimi Raikkonen, Fernando Alonso and Jenson Button – for some aggressive driving over the start of this campaign.
And although his actions have put him under the spotlight, he says that criticisms have left him totally unmoved because his bosses are happy with what he is doing.
"At the end of the day I am here to fight for my team and to give my very best for my team," he said ahead of the British Grand Prix.
"People are working day and night for you to make this team go a bit quicker, so I maximise everything I have got.
"And if that means I upset other drivers or other people, I really don't care. I just want to do the best for my team and I will keep doing it until I retire.
"I will always try to give my very best for the team I am driving."
Perez says his only regret over the opening part of the campaign is that he has not had the car to fight with the likes of Alonso and Raikkonen on even terms, so has had to take his chances with them.
"I think it is a bit of a shame that I cannot be that often fighting with those guys," he said. "I would definitely like to be in a different position.
"Right now I am fighting hard and, if they are in front, I have nothing to lose. So I fight them differently. I have a lot of respect for all of those guys but on the track they are one more rival."
