One given especially for new employees who have never celebrated Halloween at work is for them to ask their managers what is considered the norm as far as donning a costume, Insider reports.

"Your office might have strict rules--or could be completely lenient--but you don't want to be the last one to know, either way," Insider notes.

And while HR and management at some companies may be all Gung-ho about Halloween and really encourage their employees to dress up, they will want to be mindful not to put pressure on colleagues who are not fans.

"Though it's not wrong to encourage team participation, dressing up for Halloween isn't a required work task," Insider reports. "Keep in mind that many people don't celebrate the holiday for both religious and personal reasons, so costumes and other festive activities shouldn't be forced upon any employee."

The highly partisan political battles and heightened awareness around the #MeToo movement have made this year more complicated, the Palm Beach Post reports.

"Employers are very attuned to [the] fact that Halloween costumes could become a sticky question," says Brooke Ehrlich, a South Florida employment lawyer with Serota Helfman Cole & Bierman.

Employers most likely won't have to wait until Halloween to learn about at least one costume that has already drawn wide-spread condemnation. Online retailer, Yandy, late last month stopped selling an outfit that would be familiar to fans of the Hulu series, "The Handmaid's Tale," CNN reports.

The show is about a society that treats women as property, subjecting them to torture, rape and death. They are made to wear long, red loose dresses covering their entire body, and forced to live with wealthy families where they are repeatedly raped and then forced to deliver their child and give them up.

Yandy's provocative "Brave Red Maiden Costume," came with a product description noting: "A upsetting dystopian future has emerged where women no longer have a say. However, we say be bold and speak your mind in this exclusive Brave Red Maiden costume."

Yandy quickly backtracked following the widespread outrage. "Over the last few hours, it has become obvious that our 'Yandy Brave Red Maiden Costume' is being seen as a symbol of women's oppression, rather than an expression of women's empowerment," the company noted. "This is unfortunate, as it was not our intention on any level."

Ehrlich also noted that employers need to ensure there is no ambiguity over costume policies and to definitely steer clear of costumes that satirize or poke fun of political figures and religion. Also, employees should understand that work comes first and that means not wearing any type of costume that would interfere with their productivity.

"If you're a physician meeting a patient, you wouldn't want to be dressed as the Grim Reaper," she noted.

Employers also can't assume that their employees know what the policy is just because it is in writing. They must be proactive in reminding them. "For all the work and effort employers put on producing good policies and guidelines, none of it will work unless you communicate it to employees," Ehrlich said.

HR also will want to be mindful of Halloween costumes that make fun of an employee's culture or traditions, says Sharon Schweitzer, modern manners expert and cross-cultural business consultant. So reports Reader's Digest. 

"In many cultures, each stitch, sandal, makeup application, or earring has significant meanings cultivated for distinct and important purposes," Schweitzer said. "Portraying this in any manner that lessens that initial significance can be dehumanizing."

Employees also should be mindful that what they wear one Halloween season may be something that follows them for a long-time and that could become embarrassing in the future, says etiquette expert Thomas Farley. "If you're going to be photographed (and you will) and the pictures end up on social media (and they will), is there anything that will come back to haunt you?" Farley asks.

The lesson is to factor in how your costume may impact your current and future career.
