    Cakan is a successful businessman from Montenegro, who has earned himself nicknames(昵称)like “the best boss” and “Brother” by being surprisingly generous to his employees.

    Cakan, who owns "Cakan Sports", the largest sporting goods store chain in Montenegro, has been making news headlines for years, but not for his professional success. He is best known for the generosity he shows to his faithful and hard-working employees. The businessman firmly believes that his company can boom only if he keeps his employees happy, and to that end, he has offered the best of them some pretty unbelievable presents.

    Cakan first surprised his workers back in 2012, when he offered four of them brand new cars — 2 VW Golf 6 and 2 VW polo — complete with paid insurance. They were some of the oldest and most hard-working employees of Cakan Sports, and since the company had recently moved its operations outside the city, Cakan thought his best people shouldn't have to struggle to get to work. "When we saw them, we were speechless," Danijela, one of the receivers, remembers. "While the boss was saying 'his is a gift for you', all I could think of was 'this is not real, this can't be happening to us'.” But this was just one of the generous ways Cakan has rewarded his employees over the years. In 2014, after hearing that one of his workers had been saving up his paychecks so he could buy a ticket to the world Cup soccer final, in Brazil, he took him there himself, at his own expense.

    Asked why he doesn't use cheaper means of motivating his employees, like a small raise or a cash bonus, Cakan had this to say, "Money comes and goes, but memories are forever." Asked why many of his employees call him "Brother", Cakan told a reporter that it was because "brothers always help each other".
