Shareholders of more firms are rebelling over plans to increase pay packages for senior management.
A significant number of investors in Reckitt Benckiser, Shire, Standard Chartered and Weig Group have voted against motions to increase executive pay.
Engineering firm Weir Group saw its new salary policy rejected by an incredible 72% of shareholders. Pharmaceutical manufacturer, Shire, planned to give chief executive Fleming Ornskov at 25% increase to his pay package, but that was rejected by nearly half of its shareholders.
Weir's vote is binding, meaning the board must now come up with a new proposal, or maintain its current pay policy. Shire's vote, however, is not binding. It can still go ahead with Mr Ornskov's pay rise, but it would cause huge unrest among a significant portion of its investors.
On Thursday, founder of advertising giant WPP, Martin Sorrell, defended his £70 million pay package after increased media attention and shareholder scrutiny.
Earlier this month, nearly 60% of BP's shareholders rejected the company's plans to give chief executive a 20% pay rise, which would've given him an extra £14m a year. Investors felt it was unfair to give Mr Dudley such a large pay rise, given the thousands of job cuts and falling profits announced by the company.
This week, a report by Legal & General suggested that the growing gap between pay in the boardroom and on the shop or office floor would be a "hot topic" for investors in 2016.
