Ties or no ties?

I’m on temporary assignment at one of the resorts in our group where non-uniformed male staff members are not required to wear ties, unlike at most of our city properties. 

Admittedly, I’m old-school when it comes to dress standards and regard ties to be a “must” for establishing a professional business setting.  This has been my practice while managing both downtown hotels and beach resorts. 

But, it’s becoming more clear to me that many of my peers (especially the younger ones) don’t agree and are content to shed the tie themselves and omit them from their staff members’ dress code.

An argument for keeping ties is that their formality generates a more “in charge” look that other staff will model and that guests will perceive as a marque of professionalism.  

However, if most of my guests don’t wear ties, does my tie make me look stiff?  While I don’t mind appearing old-school, I do want to be approachable and open to guests and staff. 

Lastly, could this simply be a case of “When in Rome, do as the Romans do?”

Where do you stand? Ties or no ties?
