The survey also found that just 41.4% of respondents linked competitive base salary with their ideal employer, and more than half (54.1%) have not applied for a new job over the past 12 months.

Yet with job lay-offs and cost-cutting initiatives, employee engagement is low. When the economy picks up, these employees will be looking for new opportunities, and employers will be faced with a challenge: how to deal with rising attrition rates and at the same time meet new market demands.”
