下僕社畜のハーレムリベンジ！転職したらムカつく女上司どもより上の立場になったので三人まとめてほじくってわからせてあげた

Sort of blackmail. Basically protag worked at a company and was given shit by the three women that appear at the start. This drove him to eventually quit his job at that company, but he manages to get a job at a company his older brother started. One year later, the older brother's company has surpassed the company the protag was originally working for, and the three women that used to give him shit found themselves working there under him. The rest is self explanatory.

Mind control or blackmail wtf?

blackmail more like

rape tag?
