How should one deal with the bad leadership, or bad Project Manager?

Thanks 

You do not need to deal with. Him-her, just do your tasks-mission and avoid any kind of conflict

Regards  

Thank you for the invitation

I agree with colleagues answer

Thanks for invite -

You can just do your job (Complete) if you are an employee ( It's easy) - Section Manager you need more patience and try to explain your idea or you plan or any thing you see it's correct if you see there is nothing from the other side - still do your job as what they want     !

Its more happen specialy in these days !!!

3 important things are needed in such situation:

1. Wisdom

2. Patience

3. Perseverance 

Appreciation for your invitation. In such case I recommend you to do your job definitely and precisely and try to be more patient with any bad instructions or behaviors may issue from him. No need to make any conflict with him during daily work and achieve your tasks as requested till Top Management discover his lack in his leadership.

Reaction depends on what you call it " bad " . Good & bad are situational dependent . For example to resolve an emergency situation , management might force its viewpoint at expense of others which is not bad in emergency but forcing ones idea on others is bad in normal circumstances . So good and bad are subjective terms .   

Carry out your job correctly and better to explain where required t o boss

The good one is often do not try to get into direct one-on-one meetings. If we can manage the project needs to be reduced your scope and get relief from other duties that are chewing up  time.
