TheStreet's Jim Cramer says Friday's jobs number will be very important because if it's strong again, people are going to say the Fed has to move. On Wednesday, ADP numbers showed that things were weak. Numbers from Paychex, the payroll provider for small and medium sized businesses, also showed that March was weak. But on Thursday we got jobs claims data that showed the number of Americans who applied for unemployment benefits dropped last week. Friday's report from the Labor Department is expected to show an increase in nonfarm payrolls of about 250,000 in March. Cramer says on this one, he's expecting the low end of the number but not by much.
