How do managers impact negatively on employees?

Thanksfor invitation 

Agree with Mr. Omar Saad's reply.

Good question!  I think that managers can have a negative impact if they do not treat their employees like a team and/or use their managerial position to intimidate or demean their employees.

You know, its so difficult to work  under a lot of pressure, so if manager acting negatively, employees may remain under pressure then easily can make mistake, cant focus the job

Manager when it is incompetent

Would negatively affect the company's business

Being bossy ( Old School )

Poor Communication skills

managers can impact negatively on employees when they are giving negative feedback, not thanking the hard work staff  & not following the leading by example as well especially when he is estimating their performance & the manager himself has poor performance

Thanks

Well... There are many ways can be followed by manager to impact negatively on the team in general or on one of its members which will lead to collapse of either the team or employee will leave the organization or at least the department where he-she works with... some of mentioned ways:

• Negative spirit which broadcasting by manager or manager who deal with frustration manner with others.
• Inhibition of staff and kill their creativity.
• Discrimination between employees on the basis of color, sex, race.
• Manager who does not admit with his team- employee achievements
• Superiority dealing with employees.
• Successful fighting against staff by manager.
• Not to upgrade or reward employees.
• Increased workloads and tasks on the staff , and forced them to work outside the daily working hours always without overtime.
