The Senate of Mexico unanimously approved the so-called 'Chair Law' to regulate working while standing for long hours. This law establishes that workers must have chairs with backrests for rest during the workday, or take periodic breaks when their duties can only be performed standing.

Prolonged periods of standing work can cause back pain, leg swelling, blood circulation problems, foot pain and muscle fatigue. With the 'Silla Law', sanctions are expected for employers who fail to comply with the provisions, as well as the suspension of activities in case of recidivism.
