The bossiest Zodiac sign you will ever come into contact with is definitely Aries. The star sign is highly outspoken and doesn't truly consider other people's sentiments.
Being friends with or, worst yet, dating someone like that can become a touch tiresome, but Aries is undoubtedly a force to be reckoned with in the job. They are efficient in their work.
Scorpio is extremely dominating, but in a negative way. Scorpios are bossy both in and out of bed, as anyone who has had a close relationship with one will attest.
Additionally, while their domineering character can be enjoyed in bed, it is not as enjoyable outside of bed. There is no way you can go a different direction with your star sign; they want you to live by their rules.
The perfectionists of the zodiac are Virgos. They aim for perfection in all of their efforts. Yes, people frequently exert too much effort to reach the desired level of perfection, but that is a subject for another day.
Until you get to know Sags well, you won't realize how carefree and unassuming they can be and how dictatorial the zodiac can be.
The fire sign is bossy when it wants to be. Being the boss at work or even in their clique doesn't matter to them.
