I would try to remain calm and not assume that you are being laid off.  If you see things on your calendar missing.. then you can directly ask your manager why your calendar appears to have been cleared.  It may be that they aren't laying you off at all.. 

I will say that sometimes stuff like that happens in the business world..they need to reduce head counts.. and sometimes they find they had to reduce more than they originally thought.

RE the FMLA request.. was it recent and was it approved?  maybe this is because you will be getting that time off.

They cannot fire you BECAUSE you applied for FMLA.  They can fire you for any other legal reason.. and it could include that they do not need your position any longer.. or that you have not been performing to their standard.  Filing FMLA won't give you any protection from being fired for cause necessarily.

I can def sympathise with you if this comes more out of the blue.. because I  had something similar happen when I worked in public accounting for a big 6 firm.  We knew they were going through some reductions and everyone who was laid off was told on Monday.. whew.. I was safe right???  Uhmm well... got called into a partner's office on Wednesday.. and told they had to make further cuts..and I was one of them.  I honestly was not totally surprised to be on the list.. the company lost the major client I was assigned to and I was several years older than the other first years... because I came in after getting my masters not undergrad.  I think they maybe thought I was not as likely to stick around.

I would definitely polish up your resume.. but I would ask your manager why the calendar is clear.. and if you truly think this place is causing so much stress that you needed to file that claim.. it's probably not the best place for you anyway..

When I was in the semiconductor industry I made it through 9 RIF actions over 8 years and was impacted in the 10th.  I was a Sr. Manager at the time. 

The first step was an all Sr. leaders meeting to inform that we were to rank and rate all of our employees.

Next was a meeting to review everyone in each organization that was "elegible for reduction".  That meeting, all 30 of my team were on the list.  So, I went back to my office, packed and took all of my work product, etc... to my vehicle. It all went home that night. I also backed up all of my electronic work product, etc... to an external hard drive.  I still use it to this day.  22yrs later. In fact, I am mining it now as I build the structure and implementation plans for building a brand new organization for my starting Wk 3 new employer.

The next meeting was to provide all of the RIF packages to the manager and to train the managers in the process.  I received a package for each of my entire team.

At COB on the following Tuesday an all  hands meeting was held announcing that RIFs would occur the following day.  They waited till market close to avoid impacting stock prices.  The next day, I met 1:1 with all 30 of my team and provided them their RIF package. It was actually a fair package. Everyone was carried on payroll and with full benefits for 8wks.  Severance was paid on top of the 8wks based on level and years with the company and included insurance.  The company emptied one of their smaller office bldgs and set up an employement center staffed by an outplacement service provider.  Access to that was for the duration of severance each person was eligible for.

By mid day the company announced the all clear at an all hands announcing that everyone impacted had been notified and processed out and everyone had the rest of the day off.  Which was baffling to me. I had no organization. After that meeting, my desk extension rang. My boss wanted to see me in the conference room.  I walked in, handed him my badge and my pager, signed the papers on the table and turned to leave when he stopped me.  He had to go through the shpiel. I told  him I had given it 30 times that morning, He insisted. So I sat for about 5mins with him in tears going through it. Then I had to go to the outprocessing room.  I was in there with about 50 other Sr. leaders.   I was in good company. Most of us had received recent promotions or top reviews. 

After his tearful reading of the script  my boss insisted that my wife and I attend the dinner we had been invited to at his  house for the upcoming Friday.  We went.  Talk about being the turds in the punchbowl.  I never even considered not going to the party.  When we knocked on the door and walked into the house it was like a pause in a twilight zone episode.  We stayed for a few hours.  Almost everyone engaged us in conversation.  We got a number of comments about how classy it was for us to attend, etc....  The others my boss released did not attend. So yes, I went Rags on the situation.  We went, DW was radiant, I was my usual self.  I still get a rare but occassional comment from former colleagues upon occassion about that party and how our arrival stopped the music.

My entire severance counting the 8wks on payroll was 42 weeks.  That included the company carrying full benefits for me and my family for that entire 42wks.  As a Sr. Manager with 8yrs with the company I had solid severance. Lower grade codes and people with less tenure still ended up with on average of 15wks of severence.

I have had to release far more people than I want to remember due to business and industry down turns, mergers and acquisitions, etc. It sucks almost as bad to release someone as it does to get released.  For met, it is harder to RIF someone than to get RIFd. 

I have never fired anyone. Those who get fired fire themselves.  For those, I just do the paperwork.   But I have had to RIF far too many great people due to no fault of their own. That sucks.

I hope your outcome is the one you want.

Take care of you.

It really sucks
