I work for a small marketing research firm.

The policy with this company, like many, is that attendance is important. I very much agree with this companies "three strikes and you're out policy", where if you have three no-call no-shows, you're voluntarily resigned from your position.

My situation, I have had two no-call no shows (completely my fault, took full responsibility for them and lost production bonuses for weeks after they occurred).

This last Tuesday, 3/5, I call on a day I work to request a shift switch from that Tuesday to Saturday, 3/9. You can switch your shift anytime, as long as you make it up during the pay period that runs two weeks.

When I called for this change, I spoke with my manager. They got the switch taken care of, so my Tuesday shift was canceled and was to be made up on Saturday, the 9th. No problem.

I also, while on the phone, requested some extra day hours that were available only for this one week. I asked for a earlier day shift for extra hours on Friday, the 8th. They added that to my schedule.

I wrote all of this down, like I usually do when I call work or when I change schedules of any kind, not just for work, but to make sure nothing goes wrong and I am where I need to be. I got hard on myself to make corrections and notes after my other 2 no-call no shows.

So now my Tuesday, the 5th, was free. I was already scheduled off the Wednesday (6th) and Thursday (7th) after.

I come in to work early in the morning for my extra hour shift for Friday I added on the Tuesday call to my manager.

Two to three hours into my shift, a supervisor came over to my station and said I needed to sign a piece of paper for a missed shift from Thursday night. I was confused and said I wasn't scheduled last night (the 7th), and he proceeded to tell me that when I called on Tuesday to switch my shift to Saturday, that I also added a Thursday night shift.

I told him that I certainly had not said a thing about adding a shift Thursday, because of prior commitments on my calendar, which is why I did not schedule myself Thursday in the first place.

He said I could talk to my manager when they get in since that's who I talked to on the phone.

I didn't sign any "awareness sheet" (what the paper's called) with this supervisor.

Half an hour later, my manager comes in and comes to my station:

"You DID schedule a night shift Thursday, along with the make-up shift Saturday and your extra day hours for today (Friday). I would not have written it down and added it to your schedule if you had not told me that's what you wanted. You told me you wrote it all down when I was on the phone with you." I went into telling my manager I did write it all down, but I am definitely sure I made no mention of anything about Thursday, and in between the time when my supervisor first came around with the paper, and this point, I went on break and made a call to my roommate to check the calendar and my notes on the fridge to verify, and they said it was only for the switch to Saturday and Friday extra shift.

My manager then pointed to a sentence on this "awareness sheet" about voluntary resignation and termination on the third no-call no show. They muttered "well this is usually what happens", and I asked if we could go into the office and discuss, for I had no other proof than my word and my piece of paper and calendar at home detailing what I talked with them about on Tuesday.

My manager then gave me another paper to make up the no-call no show hours, and I got confused. If they were so sure I scheduled this Thursday night shift, skipped it and made no call, why am I not getting fired? Why am I being asked to make it up?

The policy is voluntary resignation from your position upon third no-call no show.

I signed both papers (may have been a stupid move, but it was after I initially stated to both supervisor and manager than I did not schedule a shift for Thursday and asking to go talk in the office instead of among coworkers that were on calls, my agitation was building.)

The paper I signed was for the actual switched shift from Tuesday night to Saturday, which would be null and void anyway if I had my third no-call no show, I had to sign to verify I switched that shift, which was accurate.

I KNOW IN MY WHOLE BEING I DID NOT MENTION THURSDAY anywhere in that conversation on Tuesday. I finished my shift and left with no answers.

Should I take it to corporate? It's a phone call away. I am so upset with this situation because it's so frustrating to be so sure of something, then to be told I'm lying.

All I know is that I am completely positive I did not mention adding a Thursday shift, because of a previous commitment that was the reason I didn't schedule myself Thursday, anyway.

I hate feeling like a liar, especially to my work associates and superiors.

I've updated and heavily shortened this question under same category, but question is:

Employer says I was a no-call no-show for a shift I am adamant I did not have scheduled. What should I do?

Very short, I promise you all! Thanks!
