How much a employee should except during an interview?

Understand your value to the construction employer. Before deciding how big a raise to request, or the total benefit package for a new position, you need to find out what other people earn for performing similar functions. In order to replace you, or to hire someone with your credentials, the construction employer is going to have to pay more or less the going rate, which you can use as a benchmark. The Bureau of Labor Statistics publishes the Occupational Outlook Handbook, available in most libraries. This annual publication gives detailed construction salary information organized by construction industry. Another source is the "American Salaries and Wages Survey," edited by Helen Fisher. To find out how salaries break down by specific region, try the Economic Research Institute’s "Geographic Reference Report."
