RE: Attitude Problem at Work

Dear [Name of Employee]:

This is a formal warning letter that follows two oral warnings about your attitude at work.

You have been orally warned on [DATE] by [Name of Person], your direct supervisor and on [DATE] by [Name of Person] from the Human Resources Department that your language in the workplace does not reflect a professional attitude towards the work and your colleagues.

As you have failed to stop using offensive language after two oral warnings, it appears that you do not take the warning seriously. This is the reason we are sending you a written warning.

Your project manager has requested this formal warning to inform you that if you don’t immediately change your attitude, you may be terminated as per the employment contract you signed on [DATE] when you joined the company.

We have high expectations of all the employees in this company to maintain a professional and cordial attitude at work. You have not followed this requirement and must do so immediately or reap the consequences.

You are an asset to the company as you produce excellent work, so we would not like to dismiss you.

However, the atmosphere in the workplace is important for all employees, and you must immediately abide by this warning.

Enclosed please find a copy of this letter which you are requested to sign and return to Name of Sender.

Employee Warning Letter For Late Attendance

RE: Formal Warning Letter for Late Attendance

Dear Mr. Miller:

This letter is to serve as an official written reprimand for an incident that happened on 07/02/2021. 

On this said date, you were one hour late to work and violated company policy. You had no written reason for being late and advised your supervisor that you overslept.

This is to serve as a written warning, as you have already been giving a verbal warning in the past two weeks. We expect all employees to come to work on time and to be ready to work.

We value attendance and consider it to be a significant factor in your position. Our goal is to service our customers with quick and effective service, and your attendance problems are not acceptable.

Because we are an installation company, we had to rearrange our route for the day to accommodate your tardiness.

Because of your late arrival to work, we had to have someone else step in and cover routes to make up for the missed service call.

We tried to call you several times to no avail, and we were not even sure you were going to show up for the day.

Our employees must be dependable, as our customers depend on their prompt arrival to their schedule appointments.

This is a disservice to our customers and to the employees who are covering for you. The employee that covered for you on both occasions is now into overtime hours.

This is not the first time that we have had this issue with you being tardy. Absenteeism was a problem in the recent past and it seems that the verbal counseling has not been effective.

Consequently, this will be the only further notice you will receive regarding this matter. Proper attendance and being on time is necessary for the overall functioning of our company.

A copy of this letter will be put in your office personnel file. Kindly treat this as an urgent matter.
