Mr Macron criticised the move as merely a photo op intended to exploit the situation
The man hotly tipped to become the next leader of France was jeered as Ms Le Pen scored a political coup over the centrist candidate during a visit to Amiens, Mr Macron’s hometown.
Marine Le Pen, who has temporarily stepped down as the leader of far-right party Front National, went to the picket line of a Whirlpool factory in France’s industrial north in an unannounced visit.
Workers are striking over the prospect of losing jobs to Poland, and Ms Le Pen was greeted warmly and snapped taking selfies with the workers as she pledged: "With me, their factory won't close!"
Meanwhile her 39-year-old rival was several miles away meeting with their union representatives, with photos from the office in stark contrast to jubilant scenes outside the factory gates.

Emmanuel Macron and Marine Le Pen
Mr Macron criticised the move as merely a photo op intended to exploit the situation for Ms Le Pen's own political benefit, stressing he was seeking to achieve long-term solutions.
But workers did not agree, and after Mr Macron’s meeting with the local chamber of commerce he too hot-footed it to the factory where he did not receive a warm welcome.
Booed and jeered, he was shouted down by strikers as he attempted to address the crowds, with one woman repeatedly shouting: ”There is no work!”

He managed to say: "It's important not to feed anger but to be up to meeting expectations.
“Of course there's anger in the country, there's anguish, there's a responsibility to take, that's why I'm here."
Both candidates are ramping up their campaigns after they made it through the second round of voting, with Mr Macron receiving 24.01 per cent to Ms Le Pen’s 21.3 per cent of votes in the first round.
As France gears up to go to the polls again next month, both parties are attempting to shore up support and ensure their message gets out there to clinch the crucial votes on May 7.
Mr Macron receive a boost after former President Nicolas Sarkozy endorsed him.
A member of the centre-right Republican party, Mr Sarkozy threw his support behind Mr Macron and his En Marche (On The Move) party after François Fillon, the Republican candidate, was knocked out in the first round.

He wrote on Facebook: “I consider that the election of Marine Le Pen and the launch of her project will bring serious consequences to our country and to the French.
"I will therefore be voting in the second round of the presidential election for Emmanuel Macron.
“It's a choice of responsibility, which is not in any case a support for his project."

Ms Le Pen looks to have sought to make herself more electable by distancing herself from from the right-wing Front National party and their controversial policies.
She has rebranded herself with the slogan “Choose France” and is hoping to capitalise on her rival’s pro-EU stance, hoping to pick up votes on the far-left as a result.
