Should Sheila Delegate?

​Sheila is a dedicated manager/leader who is driven by purpose and passion. She enjoys her employment and has no difficulty coming to the office early and staying late. She feels it's her way of showing her team about commitment and loyalty. Others see her as  a hardworking, engaging, and extending herself to meet the needs of her team and customers. Sheila also has a habit of taking on work she should delegate to others. She feels she is protecting her team members from over-work and stress.  She says, "I would rather do the work myself, then have an over stressed workplace." Sheila has made an interested choice which may lead to her own burnout. What other choices does Sheila have? Is this the choice you would make?
