You talk one way to your grandparents, another to friends, another to your boss. That’s not three people. That’s range.

Adjusting your register for different people is a skill, not a dishonesty. The vocabulary you use with a grandparent, a friend and a manager differs because the relationships differ, and reading a room correctly is among the more useful things a person can do. Being identical everywhere is not integrity, only a narrow instrument.

What matters is whether your values travel across all three, not whether your words do. Check that the person you are at work would recognise the one you are with friends. If so, the range is doing its job.
