The number of companies offering their employees health and wellness programs has soared over the past five years, with 66 percent having expanded programs to boost employees' well-being.

That's according to a survey from Robert Half company OfficeTeam, which finds that not only are employers taking more note of employee health and wellness, but employees are noticing their efforts, with 89 percent saying that their company is supportive of their wellness goals.

Among the innovative ways employers are looking to improve their workers' lot in life are some pretty imaginative (and sensible) strategies ticked off by HR managers in their responses. Older strategies, such as having a nurse's department in the office, are fading away while the latest initiatives weren't even glimmers in the eye of an HR professional only a few years ago. They include:

• Paying employees extra money if they don't check work email while on vacation

• Offering on-site exercise, meditation, yoga and healthy cooking classes

• Providing free massages

• Giving workers fitness tracking devices

• Offering on-site personal trainers

"Since professionals spend so much of their time at work, health and wellness programs aren't just nice to have—they are becoming a key factor in employee job satisfaction and well-being," Brandi Britton, a district president for OfficeTeam, says in a statement, adding, "Not offering these benefits can put a company at a disadvantage when it comes to staff recruitment and retention."
