Precedent versus Precendence

Hello all,
Recently, I've read a text written by an educated person for whom English is the native tongue.
She wrote...
"Also, it is expected that any business requirement or emergency will take precedent over a planned early departure."

Should it not have been "... will take precedenCE over..."?
Or has my grammar been flawed for years!

Thanks in advance for your input.

You're right. It should be 'precedence'.

Indeed it should be "precedence", but it's easy for me to see how that sort of error can happen.
