Depends in what you do for the company.

If they just need you to get more work done, you may be right.

But if you got a skill no one else at the company has, they are rather nice to you.

When you have the unique skill, you're better off being labelled as 'consultant'. The terms might be used interchangeably yet I've seen the power dynamics being consultant > full-timer > part-timer > contractor.
