This is what I found in article:"
Why was Demoulas fired?
Again, going way back here. But the board has held that Demoulas spends money unwisely—including through business deals that could be seen to be self-interested. (Monday’s rally was held at a Market Basket store that leases through a company owned by Demoulas’s brother-in-law.)
Much of the story stems from resentment between Demoulas and his similarly-named cousin Arthur S. Demoulas. The two Arthurs hate each other, partially as a result of Arthur T.’s side having stripped control of the company away from Arthur S.’s many years ago. Several years ago, after a wild run through the legal system, the courts said they agreed with that allegation and helped restore Arthur S.’s stake in the company.
Arthur S. gained control of the board of directors last year by swaying a shareholding family member to his side. The board then tried to fire Arthur T., but employee action delayed that move. The board next acted to take hundreds of millions of dollars out of cash reserves and deliver it to shareholders, to Arthur T.’s objections, before firing him on June 23.
Here is why the employees remain loyal to the CEO:
Why the loyalty?
Employees at Market Basket receive very strong benefits, including participation in a profit sharing program. The company has historically also promoted from within, and it’s very normal for upper management to have worked for the company for several decades. Employees are worried that new leadership wants to operate the company in a way that stresses profits. (Market Basket is already profitable, and does billions of dollars in revenue with its 71 stores.) This could, theoretically, threaten those employees’ livelihood. Gooch and Thornton have said they intend to keep those benefits in place.
Employees also worry new leadership aims to sell the company; Thornton’s expertise historically has been in mergers and acquisitions. They say they are fighting for the preservation of the company. Moreover, they say it’s also about Demoulas himself, whom they hold in extremely high regard.
It is indeed unusual that management and rank-and-file employees would be participating in a movement together in support of an ousted executive, which might be one reason why employees have resisted the idea of unionizing.
