Labor Law: Clauses, Ius Variandi, and Employment of Minors
Permitted and Prohibited Clauses in Employment Contracts
Permitted clauses are those that the parties may freely agree upon and that impose duties higher than those required by law or improve conditions in favor of the worker (e.g., increased vacation time). They do not include regular aspects that are not covered by law. Prohibited clauses involve a waiver of rights under labor laws, which is not legally appropriate in light of Article 5 (principle of irrenunciability).

Earth’s Magnetic Field and Rock Magnetization
Types of Rock Magnetization
a) Sedimentary Rock (Detrital Remanent Magnetism)
Origin: Magnetic minerals align with the Earth’s magnetic field during sediment deposition. This alignment is locked in when the sediment lithifies into rock.
Example: Magnetite in sandstone aligns during deposition and retains the Earth’s magnetic field direction.
b) Metamorphic Rock (Thermoremanent Magnetism)
Origin: During metamorphism, rocks heat up and lose their magnetization.
