It shouldn't. You can pay to run a background check on yourself if you want. If you completed deferred successfully on that charge and you haven't been convicted of anything since, you probably qualify to seal the entire thing from your record with a petition for nondisclosure. Contact any local criminal defense attorney if you'd like to hire someone to do this work for you. It sounds like it's worth it for you. It's best to do it sooner rather than later since it can take 6 months or even longer for everything to clear up, and if you pick up any convictions, you no longer qualify.
Successfully completed deferred adjudications will show up on your criminal record. As my colleague pointed out you can apply for a non-disclosure order, however, there are 23+ exceptions as to who can still see this non-disclosed information. In my opinion, the exceptions practically swallow the rule.
The fact that you did work release will not show up on your record if it was done "as a condition of community supervision." If on the other hand, it was done as jail time to sentence you on the deferred, it will show up that you served time on the DWLI.
Ultimately, while it is never good to accumulate any kind of criminal record, I would not be too concerned about a DWLI offense showing up on your record, because (again in my opinion) it is not one of the major infraction categories that employers are looking for (i.e. drug/alcohol abuse issues, violent offenses, theft and other crimes of moral turpitude).
Good luck to you!
This answer is for informational and educational use only. This answer does not create attorney-client relationship. For more details, I recommend a private consultation with a criminal defense attorney.
I agree with Mrs. Walters and Mrs. Soyars. The two weeks that you served in jail for failing the drug test is not a separate charge. The DWLI probation will show up on your record as a successfully completed deferred adjudication probation unless you request non-disclosure of your record from the court that placed you on that probation. There is a filing fee for the Petition and a lawyer can assist you with filing the Petition; and also getting your Order signed so that it can be submitted to law enforcement agencies.
Once your record is sealed, it will still be available to law enforcement agencies and government entities. Thus, if you plan to work for federal, state or local government or any law enforcement agency, it will still be accessible. As Mrs. Soyars stated, this type of charge will not likely have an impact on employment opportunities.
