An apology sentence for quarreling with the leader

When the bid was returned to xx-xx, due to personal negligence, I entered the venue to withdraw the bid after the host of the bidding office announced the deadline for bidding, which led to the rejection of our bid, causing certain economic losses and adverse effects to the company, and also wasting all the efforts of the company's leaders, business departments and technical departments. I apologize to everyone first! Secondly, in the future work, I will redouble my efforts, hoping to make up for the economic losses and my guilty heart caused by this mistake!

At the same time, this incident deeply alerted me: we must be strict with ourselves, be serious and responsible, finish what we started, and complete it 100%. We must never relax and give up when we finish 99%, because the last 1% of the game has been lost. As the saying goes, a miss is a thousand miles away. At the same time, I hope everyone can learn from this tear and take a warning to prevent such incidents from happening in future work!

Finally, I would like to thank the failed bidding experience, and thank this self-apology letter for giving me an opportunity to correct my bad habits, which made me take a step towards success.

I am here to convey

welcome

I'm very sorry!
