Are these sales people free to demand a higher wage or refuse to return? If they are free then it is not economic injustice. It is not purely their freedom however if these people are in the US where the electronics industry is open market there is no injustice. In justice involves more the systematic procedures used to prevent people from keeping their earnings. For example many people around the world want to work for reasonable wages to include many Africans, Mexicans, Iraqis, Iranians, etc. But because of government polices they are not allowed to free bid for jobs. That is economic injustice. Additionally many government actions raise barriers too many industries for example just try to buy oil direct from a foreign country, or try to drill for oil, you will probably be in jail! That is economic injustice. The government uses systems to control oil and the economics of many countries and that is unjust. Additionally it is proof our government officials either have some disbelief in free markets or an alternative agenda.
