Wow, flashback time, as I have said in this forum before, I worked for a lot of New Car dealers. The reason I capitalized those two words is some of the former dealers I worked for deserve my respect.
Others not so much. This post will be harsh to many, but life is tough.
To this response: " I have a saying - when someone tells you (shows you) who they are, believe them.", OP's employer is obviously showing what they are with the workplace they are providing.
I worked in a store where the service manager walked around talking to his side gal out on the used car lot. I worked on the front line retail, greeting clients and writing up work orders. Two co-workers were boss buddies, rude manipulative prima donna's that worked the system to game their bonus checks, I will spare the details, I told boss I am giving you not two weeks, not four weeks but SIX weeks notice to my resignation IF this situation stays the same, I am gone at the end of six weeks. I had many years experience at that point, confident of my ability to find work. Nothing changed, there was an ugly scene in front of a customer during the 5th week, I told him your time is up you have done nothing to change things in five weeks. He left about two months later, so he didn't care either.
I agree with this quote: "Bail. Be done. Leave for your health, And do not look back."
IF the owner/supervisor/manager is not aware of the stress you are under there are greater problems in this than you can correct with 10 days more on the job.
To the business owners who are worried about "very poor form to quit with no notice" I ask, do you have other employees cross trained to pick up the work when someone dies? You should have,... read the obits, it happens every day. Maybe you are running short staff to fatten the bottom line, welcome to the new world. You want a 401k with no pension, yeah that 401k is portable, reap what you sow.
It is employment at will these days in most localities. Do you give one or two week notice, before you fire or lay off due to your biz slow downs. Maybe some do, but not the majority.
I have seen dozens of employees give a two week notice who unfortunately were living paycheck to paycheck and have the boss say the same day or the next day, collect your tools and roll your box, you are done here. The last store I worked for that happened three times in less than 7 months. Not hard to figure out what to do in this case for this employer. I gave him notice but only one week, when I retired. My manager said "I can't believe you are going, you know so much about the catalogs and the parts biz and your health is good. I said yes, and I am going to enjoy my good health in retirement, I consider it my most valuable asset. He said I wish you would have given a little more notice, I have a convention out of state next week. My reply was, yeah Greg, I noticed what they do around here when you give two or three weeks, he shook his head, you are so right, good luck.
I have never heard of an employer giving two weeks pay for you to depart early in the notice, but that is honorable.
Some employers are like the guard on ShawShank, "don't make me come down there, I'll thump your skull for you",.. you can pop it on youtube if you need a good laugh.
Olds dealer, closed the week before Christmas, no notice of a buy out by the Pontiac store down the road. "Happy New Year! At least the employees got to spend the holiday with the kids. Yeah she may have done them a favor,too,..as both car lines are gone now. That's how life works.
I got dropped due to a buy-sell a few years later, the gentleman, and he is a gentleman, who owned the biz, told us with a one week notice and handed out check's for next years vacation earned two weeks for every one, plus this weeks pay and next weeks, we were welcome to come back next week to help wrap up his biz sale or move on to interviews, all but one came back to help finish the work scheduled. I had advance notice without him telling anyone, as he told me no more parts orders for stock two weeks before inventory which was about six weeks before the closing. My year end bonus was only twenty percent of the previous years, but I was thankful to get it in addition to the PTO check just the same.
I know this is too long already, but an abusive owner whose store is gone also, thanks to the death of Oldsmobile, had a new car salesman, come in one morning when service opened, remove all the photos of his family in his office, grab everything that was his, nothing that belonged to the owner, and left. The sales staff showed up an hour later for the morning sales meeting, and one of my co-workers said E.A. will slam him in the meeting, you watch and see. Another said well he should have give notice, the first co-worker said nope not really he just fired his boss, because he deserved to be fired! The week before we were told to frack the deposits, sell the gee dee car. He slammed his clipboard on the table and hit this guy on the rebound.
I have seen general managers hang up on customers, in our dept when the phones were overloaded, picking up the phone telling the caller to call XYZ Pontiac on the other side of town, then slam it down and walk out.
Jump up on the meeting table walk around stomping in rage. Another one, bellowed like a bull when something went wrong, saying he wanted to know if a mouse let a fxrt in the wash bay, while three customers waited for write up at the sevice desk. I got more, but I am sure few made it this far
One of the best, most proactive dealers I ever worked for told me as his manager, "IF we don't take care of our employees, they will fire themselves." This dealer is still in business, all but one of the rest I mentioned are gone like the steam locomotive.
I hope you find peace and position that enhances your skills. Best of luck!
