1) I’m the boss. Do as I say.
Never say “Do as I Say”. You hired them because of their skills and experience in their field. They must have certain rights and freedom towards their work.
2) You’re lucky to have a job.
Never make any employee unsuitable by passing taunts like “You are lucky to have a job”. If you find someone wrongs somewhere try to correct them, show them the path to make things work which will show your maturity and leadership skills.
3) If you don’t like it, I’ll find someone who does.
Warning employees about losing their job is not the right way to get something done. This way they will be demotivated and unwilling to do more than the bare minimum to get by.
4) Why are you the only one who has a problem with this?
To get the best work, you need to consider their problems as your problems and contribute equally to find a solution. Helping them in their problems makes your employees happier.
5)You’re Doing Okay.
Regular feedback is very much needed. Just Saying “You are Okay” is not sufficient and they will never improve. You should tell them their improvement areas for change and better performance.
6) You have no idea what stress is.
Everyone has his own stress. You never know what someone is going through. Try to avoid saying these things to employees.
7)You Should Spend More Time at Work.
Staying longer in office never means more productivity. More work means less effective and productive. Never Force your employees to work more than 7-8 hours. Being a being you may choose to work according to your responsibilities but do not ask your employees to do the same.
