Conaie leader Leonidas Iza told AFP this week demonstrations would continue "until we have results. We can no longer hold back the anger of the people."
The action has been costly, with losses of some $50 million per day to the economy. Production of fuel -- Ecuador's biggest export -- has been halved, according to the energy ministry.
Six of the country's 24 provinces are under a state of emergency and a night-time curfew is in place in Quito, where business owners and workers in the capital are fed up with the disruption to their lives and livelihoods.
Ecuador's National Assembly will meet at 6:00 pm (2300 GMT) on Saturday to vote on whether or not to oust Lasso, a conservative ex-banker who took power a year ago and who is self-isolating after a Covid-19 diagnosis.
Protesters are demanding a cut in already subsidized fuel prices, which have risen sharply in recent months, as well as jobs, food price controls, and more public spending on healthcare and education.
The vote takes place at the request of the 47 lawmakers of the leftist opposition Union for Hope coalition.
Lasso's dismissal would require 92 votes out of 137 in the assembly, in which opposition parties are in the majority.
If Lasso is unseated, Vice President Alfredo Borrero will assume interim power and call new presidential and legislative elections.
The government has rejected the protesters' demand for a fuel price cut, saying it would cost the government an unaffordable $1 billion per year.
Both sides have accused each other of intransigence, and no negotiations have been programmed to try and bring an end to the standoff.
