On average, Americans want a pay raise of 10 percent by the end of the year, but many are afraid to ask for one, a recent survey by B2BReviews found.

More than 80 percent of Americans feel entitled to a raise this year, but only 60 percent intend to ask for one, according to B2BReviews, which polled 1,000 American employees about their experience with compensation negotiations.

The overall concern is fear, apparently; 58 percent feel apprehensive about requesting a pay increase. When respondents were asked to cite their reasons for that hesitancy, topping the list was uncertainty about how to approach the subject (32 percent), followed by fear of rejection (28 percent), concern over job security (22 percent) and fear that such a request will damage relationships with management (20 percent). Waiting for a performance review and concern over the company’s financial situation were cited as reasons by 19 percent each.

Despite the trepidation on the part of some respondents, 57 percent of Americans received a higher raise without asking for one, the survey reported. Sixty-seven percent did not discuss their salary with peers or colleagues, but 23 percent said they use their knowledge of co-worker salaries to negotiate higher raises. Three quarters would request an increase upon discovering that their co-workers earn more than they do.

B2B Reviews surveyed 1,000 American employees to gauge their perception of raises in the workplace. The average age of the respondents was 40. The breakdown of respondents was 52 percent male, 47 percent female, and 1 percent nonbinary. The generational representation was 7 percent baby boomers, 29 percent Gen Xers, 57 percent millennials, and 7 percent Gen Zers.
