The union that represents most of the 300 employees who work at the tower, CGT, lifted the strike Wednesday night, Radio France Internationale said.
Workers were taking issue with delays to repairing one of the elevators that takes visitors to the towers' first floor.
Work started in 2008, and was supposed to take two years, but the elevator is still out of use, union representatives said.
Workers said the delays have reduced the ability for the tower to welcome more tourists and have led to long lines, impatient visitors and deteriorating working conditions.
