Personal opinion, how can we fix the issue of depression employee through internal environment to work?

Actvties.

This is the magic word.

making employees feel like one big happy family by joining warm actvties and mind games also by orgnizing family outings.

If the depression is personal then he or she should be given a time off from work.   If the employee is depressed which is work related a better word will demotivated, then its best to talk to the employee and find out the cause.   Without gearing on additional compensation,  motivate the employee by praising his good performance,   invite him for lunch and discuss your plans relative to future jobs for him etc etc etc.

group therapy share our feelings could be useful ofcourse beside the suggestions of the other answers the outings , the activities & break the routine

Involve everyone in team building exercise, day out , which makes everyone know each other well when the mind is occupied then there is no way depression will be haunting anyone.

A happy work place is where people want to get in no matter its beating monday blues (for countries which have sundays off, for UAE a Saturday would be same as Monday)

Everyone want to be in positive, happy and coperative environment 

Many ways but what i feel the best are challenging the work, try to develop tasks or process, break the routine, to have clean place to work in, put some music, coffee, have a break, be funny, motivation and sometimes act weird to change the atmosphere  

the management can have an open day, invite them for a trip, take the team out, chage the employee position for a day and at least give something funny at work that they can do within the break to change the mood

call me

This is my personal opinion .do like  normal every member of your work .always smile and done your responsibilites on time you never face issue of depression  

Depression is a mental condition closely related to the inability to find or imply a solution to a current problem/problems that cause discomfort. It takes some times but when the bio chemistry in the body changes there are a lot of actions that need to be taken in consideration to change the body's bio chemistry again.

   Depression is an entirely inner problem it can be related to traumatic experience or wrong mental shaping. However, being a boss or manager you can try to help your employee by understanding how he/she deals with problem solving and understand what are the buttes that reinforce positive feed. Your employee might be active in the process of creating a solution or passive/aggressive. 

  Good ways to help are sunshine, trying to joke with them and make them smile, give them or take of them a lot of work, drinking lots of water, sports and everything that can boost neurotransmitters(dopamin and oxytocin) into the body. 

This is a very complexed problem and everybody deals with it differently, however sencierity and positiveness sure help on the work environment.

I feel it is more about ones interest, most people do not like the jobs they are doing. People should only pick up jobs that they find their interest in to avoid issues like depression at work.

Depression is a common mental health problem that impacts the health and wellbeing of individuals worldwide, regardless of age, gender or background. Over recent years, there has been increased awareness of the connection between depression and the workplace. Depression in the workplace is associated with an enormous degree of disability and significant emotional and financial cost to both employees and employers.

There is a two-way connection:

1. Stress and conflict in the workplace can contribute to depression.

2. Depression can make it difficult for an individual to perform their job, affecting concentration, decision-making, and interactions with others.

Helping employees deal with depression (or preventing it in the first place) will help both employees and employers: everybody wins.
