SUGAR LAND--April 2, 2020--Researched by Industrial Info Resources (Sugar Land, Texas)--Back in the day, Julius Caesar was warned to beware the Ides of March (March 15). If Caesar were a factory or plant owner today, he would have done well just to avoid this past March altogether. By almost any reckoning, March was not a good month for the economy. Reports released this week by the Institute of Supply Management (ISM) and the American Chemistry Council (ACC) quantify the impact of COVID-19, energy market turmoil and economic headwinds on various industries.
