The following commentary comes from an independent investor or market observer as part of TheStreet's guest contributor program, which is separate from the company's news coverage.By John Canally, LPL Financial NEW YORK ( TheStreet) -- A number of key reports due out this week will tell market participants how many jobs were added in March 2012, in what industries the jobs were added, how much workers were paid and why workers were unemployed. If the consensus is correct, the private sector economy will add more than 200,000 jobs for the fourth consecutive month, and the nation's unemployment rate will stay at 8.3%. Each month, financial markets and the media turn the monthly jobs report into the most closely watched economic indicator on the calendar. A few days later, the same government agency -- The Bureau of Labor Statistics within the Department of Labor -- will release a report called the "job openings and labor turnover," known commonly as the JOLTS report, with little fanfare from the financial markets or the financial media. Follow TheStreet on Twitter and become a fan on Facebook. The JOLTS report does not get a lot of attention, mainly because it is dated (the next report due is for February), and by then, the market already has plenty of information on the labor market in March. This information includes a reading on initial claims for unemployment insurance -- a closely watched weekly metric on the labor market -- for the week ending April 7.
