The owner of three clothing stores put the problem to me like this: "I have 14 employees, all in retail, and every month attendance is a fight. One arrived late three times, another says they didn't, and I have no way to prove it". That is the real hole in most businesses in Argentina. The Collective Bargaining Agreement for Retail Employees —the famous CBA 130/75— sets fine rules for working hours, attendance, and additional pay, but then nobody has the paperwork to back those rules up. Here I explain what the agreement requires and why keeping a proper record of working hours stops being a chore and becomes your defense.
