In my organisation there are 5 employees, taking care of Sales Activities and one Boss. All the 5 employees are relatively new however the boss is working from last 14 years. No junior employee could stick to the company for more than an year or two. now my existing 5 members team have a strong doubt that the Boss is leaking the sales enquiries to the competitors because of which they are not able to close the sales deal... The management also have the same doubt but no one has any proof against this man... Can you please suggest what should be my take in this case??
