In Canada, pressing charges isn't up to the defendant. He could take the assailant to civil court but charging a person with an offense is a complicated process and the decision doesn't even rest with the police. Investigating a crime and recommending a charge is the job of the police as an independent body tasked to protect the public. But ultimately, laying a charge against an offender is the job of Crown counsel. That said, this employee was a complete a-hole and deserved to get fired.
