Health insurance, brainstorming with colleagues and matching 401(k) plans topped the list of benefits and perks missed the most among information technology professionals who have left traditional full-time employment, according to a survey by OnForce. Thirty-seven percent of respondents cited health insurance, 30 percent listed brainstorming with colleagues and 20 percent answered matching 401(k) plans.

Commuting was ranked by 38 percent of respondents as the least-missed aspect of being a traditional full-time employee. Formal performance reviews and the holiday party followed at 19 percent and 17 percent respectively.

“When you consider that 50 percent of today’s workforce will join the ranks of the self-employed by the year 2020, and that 60 percent of IT service professionals willingly left full-time jobs to be their own boss, it’s important for companies to understand the current needs of full-time and contract employees if they want to remain competitive,” said OnForce CEO Peter Cannone.

Of the 37 percent of respondents that ranked health insurance as the most missed benefit:

• 12 percent are aged 40-49
• 10 percent are aged 50-59
• 9 percent are aged 30-39
• 3 percent are aged 21-29
• 3 percent are aged 60 and over

The October survey included 1,337 IT service professionals throughout the United States.
