Reading the paragraph,
We have been running this company successfully from the past twenty years and after having 5 branches we are going ahead and opening a new branch. This would not have been possible today because of the efforts and dedication of our management and employees. So we invite each and every employee to attend this programme as they too are a vital part of this company.
I was thinking if it is better to use "without" instead of "because of". Would you choice to use "without" also? Why or Why not.
