SENIOR = JUNIOR???

What will you do? When there's someone more senior than you in your workplace but could not perform as a senior? When he is so lack of confidence to plan and decide things but keeps asking boss what to do and getting his instructions only...sighs...even with own colleagues he dont dare to plan and discuss freely but needs boss to call for an internal meeting...3pm inform me 5pm need to complete something when he has all the time he can to tell me...playing busy this few days and when the final submission date comes then start to panic...WHY???...One year working experience and still asking questions where even few months new staff can answer...6 buildings with around 20+ drawings and yet he only do one single drawing...my goodness...so many projects in the company and he does less than 5 drawings...throwing everything to draughtman...while he himself keeps checking email again and again reading emails again and again finding all the easy and light stuff to do...How to deal with this kind of senior? If I were to overpower him its somehow disrespectful...If I were to let it be and dont care so much he is going to drag down the company productivity and also mine...sighs...HOW? WHY? WHAT can I do??...
