Many employees like their bosses, but managers still have much work to do, according to new research from staffing firm Accountemps. Nearly two in three workers (64 percent) said they are happy with their supervisors, and another 29 percent are somewhat happy with their bosses. On the flip side, a third of workers have left a job due to a strained or dysfunctional relationship with a boss. The survey also found most professionals (67 percent) don’t aspire their boss’s job.
