To an organisation you are just an employee.
The day you leave, be it through choice or redundancy, you will be replaced and somebody else will sit at your desk. Your absence will be missed for a day or two, but then the organisation forgets you.
It's the reason you see the names of people you've never heard of when you look through old files for the work you're currently doing- somebody else once had your job and they have long since faded from memory.
The organisation does what they need to do to keep going, and they have no time to grieve for lost staff because of the expectations they have to fulfil. Occasionally they make mistakes and it may come with a price that you have to pay; and you will be hung out to dry if it comes between protecting you or protecting the purpose of the organisation.
Somewhere there is a spreadsheet with your name on and, when the computer says you're no longer needed, a person you've never met will let your manager know you're expendable.
Your entire working life is dependent upon whether you are serving a purpose for your organisation.
This is why, my friends, you must not mix work with family.
Do not take your work home, cast your family aside and forget about giving time to your children. Because in their hearts you are never replaced, because when you are gone, everyday you will be missed.
If anything happens to you, it will be your family and friends who are there to pick you up when you fall. Because to them, even though you are just one person, you are their world.
So reset your priorities and stop giving so much of your life away to your work.
By all means be a good worker, but be a better father or mother, a more valuable friend, a more loving daughter, a more doting son and a more attentive partner
Your family and friends were there before you got this job and will be there no matter what you do for a living.
Invest time in the people who love you back, stop working yourself into the ground and start giving more to those that really matter.
You'll be a better worker as well as a happier person for putting up barriers between your work and your personal life.
You will never feel truly satisfied by work until you are satisfied by life...
