Can you press charges against someone for accusing you of a crime?

Anonymous

I have two questions:

1. If a person accuses you of threatening them/making threats towards them and tells your boss that, which results in you getting fired, can you press charges against that person if the accusations are false? The person in question never went to the police about the accusations.

2. If you witness something that needs to be reported, but someone higher than you (i. e a manager) finds out that you witnessed that something, and they leave you a threatening voicemail, can you press charges? The voicemail contained threats such as, “you better watch your back” “you better make sure you have all your facts together before going down this road” “I will sue and press charges against you” “if you write a negative review, you better watch out”
