lazy employee

Its not always so. At times employees become like that if the work is not efficiently organized or if they are frustrated or if there is too much of office politics for them to tackle, or if they feel they are not being paid enough, or if they feel they should have got the promotion but somebody else got it, or if increments are not proportionate to the output. Jobs are hard to come by. But many times management is at fault too. They might have been open to gossip and in process denied promotion to the right person. That sends wrong message to other staff members. Others feel that no matter how hard they work, they will not get their dues.

both of you guys are right in some point, but they got what they deserve as salary, any one that work hard get promoted as well.

Not exactly. Employees are inclined to complain about others at times simply because of perceived jealousies or ego. Employer needs to consider it fairly and not take instantaneous reactions without thinking things thoroughly. And one thing that should never be done is to send a junior person to find out something from a senior person. A proper hierarchy must exist. Things go wrong when management does things haphazardly.

be friendly is a way to make employee feel comfortable, so they not stressed out, but to friendly is a problem as you say.

they don't probably know how hard it is to find a job.

Some people just dont look hard enough

could be, but i work well on my shift, the problem is when i'm not working.
