The today's lessons's headline was not translated and I wonder what it means:
"Workers of the world unite"
Workers from all over the world could struggle together, join their forces to make it with the current lack of jobs, to resist to their exploitation by the capitalists. A bit less than a century ago workers of Eastern European countries united in a communist move. Half a century ago laborers of different countries saw their unions uniting in The International Trade Union Confederation, the world's largest trade union federation.
In the headline you mentioned, Gwendo, I think "unite" is an intransitive verb meaning "come together, join, meet with each other".
Thank you Sandy A., I obviously was wrong presuming "unite" to be a noun. (CW)
