When Rouses sent us a press release recently stating that they were giving all their employees free flu shots, I got curious about other company perks.

According to a report on cnbc.com, there are a number of national companies with outrageous (and enviable) perks.

Netflix employees don’t have a limit on vacation days. The company also does not require a nine-to-five work environment.

“There is also no clothing policy at Netflix, but no one comes in naked,” the company website’s careers page reports. “Lesson: You don’t need policies for everything.” Its policy for expensing, entertainment, gifts and travel is “act in Netflix’s best interest.” All employees are allowed $10,000 per year for health benefits. Whatever they don’t use, they get to keep.

Akraya, a staffing company in Sunnyvale, Calif., places employees in information technology, engineering, marketing and creative positions.

The company allows its own employees to work from home during rush hours to avoid the aggravation of traffic. It also sends professional cleaners to tidy up employees’ homes twice a month.

Dropbox, the data storage company housed in San Francisco, offers employees the opportunity to build or buy their dream computer. It also offers a music studio outfitted with everything, not to mention other treats such as whiskey Fridays, Laser Tag and a Dance Dance Revolution machine.

Texas-based NuStar Energy allows employee use of the corporate jet. This sounds great, but don’t get excited quite yet. It’s only for emergencies. Joe Q. Employee can’t take the jet to Honolulu.

“Last year, one of our corporate employees lost a family member in a tragic accident, so we dispatched a group of employees to Louisiana to attend the service and provide support to the family. The good news is that we haven’t needed to send the plane on many occasions, but it is available if needed,” a company representative said.

Still, it’s better than most companies offer, right?

LoadSpring Solutions, a Lawrence, Mass.-based company of about 23 employees, creates project-management software. Employees who have been with the company more than two years are granted $5,000, plus an extra week of vacation time to travel abroad.

That’s a perk I wouldn’t mind having.

Chesapeake Energy, based in Oklahoma City, has a corporate campus that features a 72,000-square-foot fitness facility, tanning beds and spray tanning, free scuba certification, and an employee garden the size of a city block. They also offer a health and dental center with dermatology treatments including Botox.

I’m not sure whether those treatments are free or merely convenient.

Genentech, another San Francisco company, is a leader in the biotech industry. Benefits for their employees include free counseling, legal advice, tuition assistance, a childcare center, haircuts, weekly car washes, dog sitting, nursing rooms, seasonal produce stands, and two libraries.

After every six years with the company, employees may take a six-week paid sabbatical.

Qwiki is a San Francisco startup that aims to change the way online information is presented, delivering it in a new audio and visual format. They are expanding their staff with the promise of perks like their promise to buy employees a bike or to allow them to expense their train fare. The company also will reimburse for membership at any gym, and they provide catered meals all day.

I wouldn’t mind that catering, but I’d definitely need the bike after working there for a few weeks.

Since 2004, Integrated Archive Systems, an IT infrastructure integrator in Palo Alto, Calif., has been offering a $10,000 subsidy to employees who purchase a hybrid car.

Wow. Just, wow.

A few other gems I found?

CNNmoney.com says Zappos.com has some of the best perks around.

Employees enjoy free lunches, no-charge vending machines, a full-time life coach on hand, and “create fun and a little weirdness” as one of the company’s guiding tenets.

Again with the free food, but this time no free bikes. I could go for a little creative weirdness though.

At Whole Foods, headquartered in Austin, Texas, new hires get a 20 percent discount card for all products sold in the stores. Employees who meet the goals of a healthy-living challenge get up to 30 percent off their purchases.

The CNN list includes the most unusual perks of the companies it listed as the top 100 to work for. Zappos, NuStar Energy and Chesapeake Energy made that list. Also on the list?

Alston & Bird, a law firm that builds a $25,000 fertility benefit into employees’ health plans; DPR Construction, which has a wine bar in each of its 17 offices (the Texas branch features an in-house saloon); and Cisco, a tech giant that brings a car care company to the office twice a week.

Kimpton’s Hotel staff can bring their pets to work (provided they play well with others) and leave them with onsite pet care specialists. The company has also partnered with Pet Assure to offer employees veterinary health insurance.

I really like this one, but the closest we have is a dog who visits us most mornings for a little socialization.

Finally, Hasbro and Mattel give their employees half days every Friday.

That’s a perk I know well. Newsroom employees here at The Daily Review also get this benefit every other Friday. It’s a little thank you for the extra hours we put in at night covering meetings so we can bring the news to you.
