Thousands of young Peruvians marched in at least nine cities protesting a new law that strips workers between ages 18 and 24 of some labour rights.
In Lima, some of the more than 5,000 marchers clashed with tear gas-hurling police Thursday night, pelting them with sticks and stones. Police did not release numbers on injuries and arrests.
It was the fourth such march since Congress passed the law in early December. Critics say it favours employers, converting one in 15 Peruvians into cheap labour.
Under the law, workers ages 18 to 24 who are dismissed don't get severance pay. Workers in the age group also get only half the vacation of older workers. And they won't be paid the twice yearly bonuses of one month's wages standard for others.
