tais-toi
fermer la bouche
ferme la porte
taisez-vous tous
That could be said 'ferme-la !' in French. Not something you would say to your boss.
The phrase "shut up" in French is "tais-toi" for singular form, and "taisez-vous" for plural form.
"Fermez la bouche!" (pronounced FER-meh lah BOOSH) is the popular way of saying "Shut up." Literally it means, "Shut the mouth." You don't say "your" when describing one's body parts. For "shut your face" you would say "Fermez le visage!" (pronounced FER-meh luh vee-SAHZH) but it may be mistranslated by a french speaker as idiocy. Also, "ta gueule !"
